This hose is listed in Porsche parts catalogues for selected Porsche 911 SC, 930 Turbo and 944 applications, where it connects components of the fuel tank ventilation or activated charcoal canister system.

The fuel tank ventilation system manages the movement of air and petrol vapour as fuel is consumed and temperature changes affect pressure inside the tank.

The hose provides a flexible passage between the specified ventilation components, helping maintain the intended vapour routing and allowing the fuel tank to breathe through its designed ventilation circuit.

Manufactured to Porsche's original equipment specification, the hose has nominal dimensions of 12 × 2.5 mm, corresponding to a 12 mm internal diameter and 2.5 mm wall thickness.

The hose is intended to be cut to the correct length for its particular installation, where supplied as bulk hose.

During normal operation, fuel tank ventilation hoses are exposed to petrol vapour, changing temperatures and vehicle vibration. These conditions can gradually affect the flexibility and condition of the hose material.

Over time, an ageing hose may become brittle, cracked, split, swollen or loose at its connection points.

A damaged hose can allow petrol vapours to escape or interfere with the proper operation of the ventilation circuit. This may produce a persistent fuel smell, particularly after refuelling or when the vehicle is parked in warm conditions.

Replacing a defective hose with a Genuine Porsche component helps restore the intended fuel vapour connections, reduce unwanted vapour leakage and maintain the original ventilation arrangement.

Ideal for classic Porsche fuel system repairs, tank ventilation maintenance and restoration projects, this Genuine Porsche Hose provides a correctly specified replacement for compatible applications.

What This Product Does:
The hose forms part of the vehicle's fuel tank ventilation or fuel vapour management circuit.

Its primary function is to provide a flexible passage for air and petrol vapour between designated components.

As the engine consumes fuel, the volume of liquid within the tank decreases. The ventilation system allows the resulting changes in tank pressure to be managed.

Changes in ambient temperature also affect fuel vapour pressure. The tank ventilation arrangement accommodates these changes through its connecting hoses, expansion chambers and other components.

In vehicles fitted with an activated charcoal canister, fuel vapours are routed through the appropriate vapour management system rather than being released freely.

The hose supports these functions by maintaining the intended connection.

Its main functions include:

• Supporting fuel tank ventilation: Provides a passage for air and fuel vapour within the designated circuit.
• Helping manage tank pressure: Supports normal pressure equalisation as fuel volume and temperature change.
• Connecting ventilation components: Links the relevant expansion chambers, pipes, fittings or charcoal canister components.
• Maintaining vapour routing: Helps keep fuel vapour within the intended ventilation pathway.
• Reducing unwanted vapour escape: Maintains a secure connection when correctly installed.
• Accommodating vehicle movement: Provides flexibility between connected components.
• Maintaining unrestricted flow: Allows air and vapour to pass through the specified hose section.
• Supporting emissions equipment: Helps preserve the original vapour management arrangement on vehicles equipped with an activated charcoal canister.
• Maintaining factory hose routing: Restores the correct hose size and installation arrangement.
• Supporting fuel system reliability: Helps prevent faults associated with cracked, collapsed or disconnected ventilation hoses.

Symptoms Of Wear Or Failure:
Ageing fuel tank ventilation hoses can deteriorate through prolonged exposure to petrol vapour, heat, vibration and repeated changes in temperature.

Common symptoms and signs of a worn or damaged hose include:

• Petrol smell around the vehicle: Escaping vapours may create a noticeable fuel odour.
• Fuel smell after refuelling: Vapour leakage may become more noticeable when the tank is full.
• Fuel smell in warm weather: Increased vapour formation may expose weaknesses in the ventilation circuit.
• Visible cracking: The hose surface may develop cracks as the material ages.
• Hardened or brittle hose: Loss of flexibility can affect sealing around the connection fittings.
• Split hose ends: Cracking near connection points may allow vapour leakage.
• Loose hose connections: Deteriorated hose ends may no longer grip fittings securely.
• Disconnected hose: An insecure connection can leave part of the vapour circuit open.
• Swollen or distorted material: Ageing or chemical incompatibility may affect the hose shape.
• Collapsed hose sections: Deformation may restrict airflow through the ventilation circuit.
• Kinked hose routing: Incorrect installation can obstruct the intended ventilation passage.
• Visible abrasion: Contact with sharp edges or neighbouring components may wear through the hose.
• Unusual fuel tank pressure symptoms: A restricted ventilation system may contribute to excessive pressure or vacuum in the tank.
• Damaged hose clamps: Loose or corroded clamps may compromise secure attachment.
• Persistent vapour odours after servicing: Incorrect routing or inadequate sealing may leave a connection leaking.

Why Replacement Matters:
Replacing a deteriorated ventilation hose helps maintain the correct operation of the fuel tank breathing and vapour management system.

An old hose may become cracked or brittle, allowing fuel vapours to escape around its surface or connection points.

A collapsed or incorrectly routed hose may also restrict the normal movement of air and vapour through the system.

Diagram Ref No 79

This rubber weather seal is fitted along the front, or leading, edge of the door, helping create a protective seal between the door and surrounding bodywork when the door is closed.

The seal is designed to limit the entry of water, wind, dust and road debris into the vehicle's interior while maintaining the original door sealing arrangement.

Unlike a complete door aperture weatherstrip, this component seals a specific section of the door assembly. It is traditionally bonded to the door using an appropriate adhesive.

The Porsche 356 features a classic body and door construction that relies on correctly positioned rubber seals to protect the passenger compartment from the elements.

When the door is closed, the front inner door seal helps close the gap between the leading edge of the door and the adjacent bodywork.

A properly fitted seal also provides a degree of cushioning between the mating surfaces, helping reduce unwanted vibration and rattling.

Over time, original rubber seals can deteriorate because of age, exposure to sunlight, moisture, temperature fluctuations and repeated compression.

The rubber may become brittle, cracked, flattened or detached from the door, reducing its ability to provide an effective weather-resistant seal.

Deteriorated door seals may contribute to increased wind noise, water entering the cabin, damp interior trim and moisture accumulation around the door opening.

Replacing a damaged or perished front inner door seal with a Genuine Porsche component helps restore the original sealing arrangement, improve weather protection and preserve the classic vehicle's interior condition.

Ideal for door refurbishment, bodywork repairs and Porsche 356 restoration projects, this Genuine Porsche Inner Door Seal provides an original equipment replacement for compatible applications.

What This Product Does:
The front inner door seal forms part of the Porsche 356 body weatherproofing system.

Its primary function is to provide a flexible seal between the front edge of the door and the adjacent bodywork when the door is closed.

As the door closes, the rubber seal contacts the corresponding body surface and compresses to help close the gap.

This reduces the movement of water, air and road contamination through the door opening.

Its main functions include:

• Sealing the front edge of the door: Helps close the gap between the door and adjacent bodywork.
• Reducing water ingress: Helps prevent rainwater and road spray from entering through the door opening.
• Limiting wind intrusion: Reduces airflow through gaps around the leading edge of the door.
• Reducing wind noise: Helps minimise whistling and rushing-air sounds caused by inadequate door sealing.
• Preventing dust entry: Reduces the amount of dirt and road debris entering the passenger compartment.
• Cushioning the door connection: Provides a flexible contact surface between the door and body.
• Reducing vibration and rattling: Helps minimise unwanted movement-related noises at the sealing interface.
• Protecting interior trim: Helps reduce moisture exposure around the footwell, carpets and adjacent trim.
• Supporting bodywork preservation: Reduces prolonged moisture exposure that may contribute to corrosion.
• Maintaining original door weatherproofing: Restores the factory-style sealing arrangement.

The inner door seal does not adjust the door hinges, latch or mechanical alignment.

It should work alongside correctly adjusted door hardware and the remaining door seals.

Symptoms Of Wear Or Failure:
Door seals are exposed to repeated compression, changing temperatures, moisture and environmental contamination.

On classic Porsche 356 vehicles, ageing rubber and deteriorated adhesive can compromise the original seal.

Common signs of a worn or damaged front inner door seal include:

• Water entering the cabin: Rainwater or road spray may pass through gaps around the door.
• Increased wind noise: A defective seal may allow rushing-air or whistling sounds during driving.
• Cracked rubber: Ageing may cause visible splits or cracks.
• Hardened seal material: Rubber may lose its original flexibility and sealing ability.
• Flattened seal profile: Repeated compression may permanently deform the rubber.
• Shrunken seal: Ageing material may pull away from the intended sealing surfaces.
• Loose or detached sections: Deteriorated adhesive may allow the seal to separate from the door.
• Torn rubber: Mechanical damage can create gaps within the sealing surface.
• Damp carpets or interior trim: Moisture entering through the door opening may affect the interior.
• Visible gaps around the door: Missing or deteriorated sealing material may leave sections inadequately sealed.
• Dust accumulation inside the cabin: Road dust may enter through poorly sealed door openings.
• Door rattling: Loss of sealing contact may contribute to vibration or movement-related noise.
• Uneven sealing contact: Distorted or incorrectly fitted rubber may not contact the body consistently.
• Visible perishing: The rubber may develop a rough, dry or deteriorated surface.
• Seal detachment during door opening: A poorly bonded seal may lift away from the door.
• Corrosion around the door opening: Repeated moisture exposure may contribute to deterioration of surrounding metalwork.

Why Replacement Matters:
Replacing a deteriorated front inner door seal helps restore the weather-resistant properties of the Porsche 356 door assembly.

A worn seal may no longer compress correctly against the body, allowing water, air and road contamination to pass through the door opening.

Prolonged moisture exposure can damage carpets, interior trim and painted metal surfaces.

On a classic vehicle, preventing water ingress is especially important because hidden corrosion can develop around door apertures, sills and lower bodywork.

Installing a Genuine Porsche replacement Inner Door Seal helps to:

• Restore effective door sealing: Renew the protective barrier along the front edge of the door.
• Reduce water ingress: Help prevent rainwater entering through the affected sealing area.
• Improve cabin comfort: Reduce draughts and wind noise associated with a damaged seal.
• Protect interior trim: Limit moisture exposure to carpets, upholstery and adjacent components.
• Reduce corrosion risk: Help protect vulnerable bodywork from repeated water exposure.
• Replace aged rubber: Renew hardened, cracked or flattened sealing material.

Pressure Hose. 
The Genuine Porsche Pressure Hose is an original equipment turbocharger charge-air system component designed for selected Porsche 911 (996) Turbo and GT2 models manufactured between 2001 and 2005.

Fits:

• Porsche 996 TURBO 2000-05
• Porsche 996 GT2 2001-05  

Diagram Ref No 4

These pressure hoses form part of the engine's forced-induction system, providing flexible connections within the turbocharger and intercooler pipework. They help carry compressed intake air through the charge-air system while maintaining secure, pressure-resistant connections.

Available in separate left-hand and right-hand configurations, the hoses are specifically shaped to match the corresponding installation positions.

99611063174 – Left-Hand Pressure Hose

99611063075 – Right-Hand Pressure Hose

The Porsche 996 Turbo and GT2 use twin turbochargers to compress the intake air supplied to the engine. This compressed air passes through the charge-air cooling and intake system before entering the engine's cylinders.

Correctly sealed pressure hoses are essential for ensuring that the compressed air remains contained within the intended pipework. Any leakage can reduce the effective boost pressure reaching the engine and interfere with the performance of the turbocharging system.

Manufactured to Porsche's original equipment specifications, these hoses provide the intended fitment, flexibility and connection arrangement for the relevant charge-air components.

During operation, turbocharger pressure hoses are exposed to changing boost pressures, elevated temperatures, engine vibration and repeated expansion and contraction.

Over time, the original hoses may deteriorate due to ageing, heat exposure, oil vapour contamination or mechanical stress. Cracks, splits, loose connections or damaged hose ends can result in boost-pressure leaks.

A leaking pressure hose may cause reduced acceleration, inconsistent turbocharger response, hissing noises or engine management fault codes.

Replacing a damaged or deteriorated hose with a Genuine Porsche component helps restore the integrity of the charge-air system, maintain the intended boost-pressure delivery and support reliable turbocharged engine performance.

Ideal for boost leak repairs, turbocharger servicing, intercooler maintenance and Porsche 996 Turbo restoration projects, these Genuine Porsche Pressure Hoses provide factory-specified replacements for compatible vehicles.

What This Product Does:
The pressure hose is an essential component of the Porsche 996 Turbo and GT2 charge-air system.

Its primary function is to carry compressed intake air between the relevant turbocharging and intercooler components while maintaining a secure, airtight connection.

When the turbochargers compress incoming air, both its pressure and temperature increase.

The intercoolers help reduce the temperature of this compressed air before it reaches the engine intake system.

Flexible pressure hoses connect sections of the charge-air pipework, accommodating engine movement and vibration while maintaining the intended airflow passage.

Their main functions include:

• Transporting compressed intake air: Carries pressurised air through the applicable turbocharger and intercooler circuit.
• Maintaining boost pressure: Helps prevent compressed air from escaping through damaged connections.
• Supporting intercooler operation: Forms part of the pipework that directs charge air through the cooling system.
• Maintaining airtight connections: Provides a secure connection between the relevant charge-air components.
• Accommodating movement and vibration: Allows limited movement between connected components without compromising the air passage.
• Supporting turbocharger performance: Helps ensure compressed air reaches the downstream intake system as intended.
• Maintaining engine responsiveness: Supports consistent boost-pressure delivery during acceleration.
• Reducing unwanted air leakage: Helps prevent loss of charge air through the hose connection.
• Preserving correct airflow routing: Maintains the factory-specified left-hand or right-hand hose arrangement.
• Supporting engine management accuracy: Helps the boost-control system operate with the expected pressure conditions.

The pressure hose does not generate boost pressure. Boost is produced by the turbochargers and managed by the associated control system.

Symptoms Of Wear Or Failure:
Turbocharger pressure hoses operate in demanding conditions, with repeated exposure to heat, boost pressure, vibration and oil vapour.

Although designed for durability, ageing materials and weakened hose connections may eventually cause leakage or physical failure.

Common symptoms of a worn or damaged pressure hose include:

• Reduced engine power: Escaping compressed air may reduce the boost pressure available to the engine.
• Poor acceleration: The vehicle may feel less responsive, particularly under heavy throttle.
• Hissing noises under boost: A split hose or loose connection may produce a noticeable rushing-air sound.
• Whistling noises: Compressed air escaping through a small opening may create an unusual whistle.
• Inconsistent turbocharger response: Boost delivery may become irregular when the charge-air system cannot maintain pressure.
• Boost-pressure fault codes: The engine management system may detect a difference between requested and actual boost pressure.
• Engine warning light: Significant charge-air leaks may trigger an engine management warning.
• Cracked hose material: Ageing and repeated thermal cycling may cause visible cracks or splits.
• Swollen or softened hose sections: Heat and prolonged oil vapour exposure may affect the material's condition.
• Loose hose connections: Deteriorated hose ends or damaged clamps may prevent secure attachment.
• Hose slipping from a connection: Incorrect fastening or damaged hose ends may allow the hose to detach under pressure.
• Oil residue around hose joints: Oily deposits may collect around a leaking connection because charge air can contain oil vapour.
• Collapsed or distorted hose: Physical damage or weakened material may restrict the intended airflow passage.
• Abrasion damage: Contact with surrounding components may gradually wear through the hose surface.
• Repeated loss of boost pressure: Persistent charge-air leakage may prevent the engine from achieving its intended boost level.

Why Replacement Matters:
Replacing a deteriorated turbocharger pressure hose is important for maintaining reliable boost-pressure delivery and preserving the performance of the Porsche 996 Turbo or GT2.

A split or loose hose may allow compressed air to escape before it reaches the engine intake system, resulting in reduced performance and inconsistent turbocharger response.

The engine management system may attempt to compensate for abnormal pressure conditions, but replacing the damaged hose is necessary to restore the original sealed air passage.

A hose with significant deterioration may also detach from its connection during boost operation, causing a sudden loss of engine power.

Installing a Genuine Porsche replacement Pressure Hose helps to:

• Restore boost-pressure integrity: Replace leaking or damaged pipework to maintain compressed-air delivery.
• Improve acceleration: Address reduced performance caused by a confirmed boost leak.
• Maintain turbocharger response: Support consistent delivery of compressed intake air.
• Restore charge-air system sealing: Ensure the hose connections remain secure under normal operating conditions.
• Reduce boost-related warning messages: Address diagnostic faults caused by a confirmed pressure hose leak.
• Eliminate unwanted hissing: Repair air leakage caused by damaged hose material or connections.
• Prevent hose detachment: Replace weakened ends or damaged sections before they fail under pressure.
• Support intercooler efficiency: Maintain the intended air passage through the cooling system.
• Reduce unnecessary turbocharger loading: Help prevent operating conditions associated with compensating for charge-air leaks.
• Maintain original hose routing: Restore the correct left-hand or right-hand installation arrangement.
• Support turbocharger servicing: Provide replacement hoses during intercooler or charge-air system repairs.

Located within the rear exhaust assembly, the clamp secures the specified exhaust pipe or silencer connection, helping maintain correct component alignment and a secure joint.

The exhaust system operates under demanding conditions, including high temperatures, vibration, exhaust gas pressure and repeated expansion and contraction as the engine heats up and cools down.

The exhaust clamp is designed to hold the relevant exhaust components firmly together while accommodating the requirements of the original Porsche exhaust arrangement.

A correctly fitted clamp helps maintain the integrity of the exhaust connection, reducing unwanted movement and helping prevent exhaust gases from escaping through the joint.

On vehicles equipped with the Porsche Sports Exhaust System, the clamp forms part of the factory exhaust assembly and works alongside the associated silencers, pipework, brackets and mounting hardware.

Over time, an exhaust clamp may deteriorate because of corrosion, repeated thermal cycling, mechanical stress or damage during exhaust servicing.

A weakened or damaged clamp may lose its ability to maintain sufficient clamping force, potentially resulting in an exhaust leak, rattling noise or movement between connected components.

Replacing a defective clamp with a Genuine Porsche component helps restore the intended exhaust connection, maintain correct alignment and support reliable operation of the exhaust system.

Ideal for exhaust repairs, rear silencer replacement, sports exhaust maintenance and Porsche restoration, this Genuine Porsche Exhaust Clamp provides a factory-specified replacement for compatible applications.

What This Product Does:
The exhaust clamp is a fastening component used to secure the designated connection within the rear exhaust system.

Its primary function is to maintain a firm mechanical connection between the associated exhaust components.

During engine operation, hot exhaust gases pass through the exhaust pipework, catalytic converters and rear silencers before exiting through the tailpipes.

The exhaust assembly experiences vibration and temperature changes, which can place repeated stress on its joints and mounting points.

The clamp helps maintain the correct connection between the specified components.

Its main functions include:

• Securing exhaust components: Holds the relevant exhaust connection firmly together.
• Maintaining joint integrity: Helps prevent unwanted movement between connected exhaust sections.
• Supporting exhaust sealing: Maintains the required clamping force at the specified joint.
• Reducing exhaust gas leakage: Helps prevent gases escaping through an inadequately secured connection.
• Maintaining exhaust alignment: Supports correct positioning of connected pipes or silencer components.
• Reducing vibration: Helps limit movement that could otherwise produce rattling noises.
• Supporting rear silencer installation: Provides the required fastening arrangement during exhaust repairs.
• Withstanding thermal cycling: Operates under repeated heating and cooling conditions.
• Preserving original exhaust geometry: Maintains the factory-designed connection arrangement.
• Supporting long-term exhaust reliability: Helps keep the exhaust assembly properly secured during normal vehicle operation.

The clamp does not control exhaust flow, regulate emissions or operate the sports exhaust valves.

Its purpose is to provide secure mechanical fastening at the corresponding exhaust connection.

Symptoms Of Wear Or Failure:
Exhaust clamps are exposed to high temperatures, road moisture, salt, vibration and mechanical stress.

Over time, these conditions may cause corrosion, distortion or deterioration of the fastening mechanism.

Common symptoms of a worn or damaged exhaust clamp include:

• Exhaust blowing noise: A loose or damaged clamp may allow gases to escape through the joint.
• Increased exhaust noise: Leakage may cause the exhaust to sound louder than normal.
• Rattling from the rear exhaust: An insecure connection may produce metallic rattling during driving.
• Vibration under acceleration: Movement between exhaust components may become more noticeable when the engine is under load.
• Visible corrosion: Rust may weaken the clamp or its fastening hardware.
• Cracked clamp body: Repeated mechanical stress or deterioration may cause physical damage.
• Loose exhaust connection: The joint may no longer remain securely fastened.
• Damaged retaining bolt or nut: Corroded or stripped hardware may prevent the clamp from tightening correctly.
• Distorted clamp shape: Excessive tightening or impact damage may affect proper seating.
• Soot deposits around the joint: Black deposits may indicate exhaust gases escaping through the connection.
• Exhaust fumes near the vehicle: A leaking joint may allow gases to escape before reaching the tailpipe outlet.
• Incorrect tailpipe alignment: A loose connection may allow movement that affects the final exhaust position.
• Movement during inspection: The connected exhaust components may show excessive play.
• Repeated loosening: Damaged threads or poor seating may prevent the clamp from maintaining its fastening force.
• Damage during exhaust removal: An older clamp may deform or fracture when removed during servicing.

Why Replacement Matters:
Replacing a defective exhaust clamp is important for maintaining a secure connection within the exhaust system.

A corroded, loose or distorted clamp may no longer provide the necessary fastening force, allowing the exhaust joint to move or leak.

Continued operation with an insecure connection can increase stress on neighbouring exhaust components and may cause additional rattling, vibration or deterioration.

An exhaust leak can also allow hot gases to escape at an unintended location.

Installing a Genuine Porsche replacement Exhaust Clamp helps to:

• Restore secure exhaust fastening: Replace a damaged clamp with the correct original equipment component.
• Reduce exhaust leaks: Help maintain a properly sealed connection where the clamp is responsible for leakage.
• Eliminate unwanted rattling: Address noises caused by an insecure exhaust joint.
• Maintain correct exhaust alignment: Support the intended position of connected exhaust components.
• Prevent unnecessary movement: Reduce vibration-related stress at the connection.
• Replace corroded hardware: Renew components affected by rust or deterioration.
• Support rear silencer replacement: Provide the appropriate clamp during exhaust repairs.
• Maintain sports exhaust integrity: Preserve the original connection arrangement on compatible sports exhaust systems.
• Protect neighbouring exhaust components: Reduce additional stress caused by loose joints.
• Support correct tailpipe positioning: Help maintain the specified alignment of the rear exhaust assembly.
• Preserve original Porsche specifications: Use the correct factory-designed fastening component.
• Support long-term reliability: Maintain secure exhaust connections under normal operating conditions.

Replacement is particularly recommended when the clamp is cracked, heavily corroded, distorted or unable to tighten securely.

It may also be advisable to replace the clamp during exhaust disassembly if the original component cannot be reused reliably.

Confirm compatibility with your vehicle’s model, production year and engine before ordering. Match the part number and interior specification as well as the model designation.

What This Product Does

The armrest provides an arm-supporting surface within the door trim. Its leather finish forms part of the cabin’s upholstery, making material and colour matching important when replacing an individual interior component.

Functions

• Provides a resting surface for an occupant’s arm.
• Completes the armrest area of the interior door trim.
• Replaces a worn or damaged leather-covered touch point.
  
  

Technical Details

• Brand: Porsche.
• Component: door armrest.
• Finish material: leather.
  
  

Symptoms of Fault

Relevant signs of deterioration include scuffed or cracked leather, surface tears and lifting upholstery. Looseness or rattling around the armrest should also prompt an inspection of its attachments and the surrounding door trim before deciding which components require replacement.

Why Replacement Matters

Renewing a damaged armrest addresses wear at a frequently used cabin surface and helps restore a consistent interior appearance. Inspect the adjacent trim and fixings during the repair; replacing the armrest alone will not correct damage elsewhere in the door assembly.

FAQs

Is model identification enough to confirm suitability?
No. Check the complete part number, production details and upholstery specification against the vehicle.

What should be checked during fitting?
Inspect the surrounding trim and attachment points. Use suitable trim-removal tools and replace damaged fixings where required.
