Rubber sleeve circlip
OE Match fuel filler rubber sleeve circlip for classic Porsche 911, 912 and 930 Turbo applications. This retaining component secures the rubber sleeve at the fuel filler assembly.

Fits

Porsche 911/912 1965 - 1969
Porsche 911 1970 - 1989
Porsche 930 Turbo 1975 - 1989

Diagram Ref No 22


What This Product Does

The circlip provides mechanical retention for the filler sleeve. It is retaining hardware rather than the rubber sleeve, filler cap or filler neck itself, so inspect the adjoining components separately when planning repairs.


Functions

  • Retains the fuel filler rubber sleeve in its fitted position.
  • Provides replacement retaining hardware during filler assembly maintenance or restoration.


Technical Details

  • Brand: OE Match.
  • Part number: 99915200400.
  • Component type: fuel filler rubber sleeve circlip.


Why Replacement Matters

Renew damaged or heavily corroded retaining hardware when servicing the filler assembly. Check the rubber sleeve and surrounding fittings at the same time, as replacing the circlip alone will not repair deteriorated rubber or a damaged adjoining component. OE Match develops replacement parts around Porsche applications, using original references and fitment information to identify suitable components.

Check fitment for your specific vehicle (model, year, engine) before ordering.

OE Match fuel flap release cable knob with emblem for Porsche 911, 912, 930, 964 and 993 applications. This replacement knob provides the hand-operated control for the filler flap release cable.

Fits

  • Porsche 911 1965-69 COUPE F 030 0255>>
  • Porsche 911 1970-89
  • Porsche 911 Turbo 1975-89
  • Porsche 964 1989-94
  • Porsche 993 1995-98

Check fitment for your specific vehicle (model, year, engine) before ordering.

Diagram ref no 19

What This Product Does

The knob gives the driver a grip for pulling the release cable and operating the fuel filler flap mechanism. It is a release-control component, rather than a tank cap, filler neck or fuel-system seal.

Functions

  • Provides a grip for manual cable operation.
  • Transfers the driver's pull to the filler flap release mechanism.
  • Renews the emblem-bearing release control during repair or restoration.

Technical Details

  • Brand: OE Match.
  • Supplied reference: 90155282200.
  • Component: release cable knob with emblem.

Symptoms of Fault

Difficulty operating the filler flap warrants inspection of the knob, its cable connection and the release mechanism. A sticking flap does not, by itself, establish that the knob needs replacement.

Why Replacement Matters

Renewing a damaged or missing knob restores the hand-operated release control. Check the cable and latch at the same time: replacing the knob alone will not resolve a fault elsewhere in the mechanism.

Fuel Flap Release Cable Knob.

The OE MATCH Fuel Flap Release Cable Knob is a high-quality replacement component designed for Porsche 911, 964 and 993 models. Manufactured to match the original equipment fit and appearance, this replacement knob provides a practical solution for restoring the operation of the fuel filler flap release mechanism.

Fits:
  • Porsche 911 1965-69 COUPE F 030 0255>>
  • Porsche 911 1970-89

Diagram Ref No 19

The knob attaches to the fuel flap release cable, allowing the driver to manually operate the release mechanism and access the fuel filler compartment. Ideal for replacing worn, cracked, damaged or missing original knobs, it helps maintain both the functionality and original appearance of your Porsche's interior.

What This Product Does:
The fuel flap release cable knob provides a convenient grip for manually operating the fuel filler flap release mechanism. When pulled, the knob operates the connected cable, which disengages the fuel flap latch and allows the flap to be opened for refuelling.

Its key functions include:

  • Fuel Flap Operation: Allows the driver to release the fuel filler flap using the cable-operated mechanism.
  • Secure Cable Connection: Provides a practical operating handle for the fuel flap release cable.
  • Easy Accessibility: Enables convenient access to the fuel filler compartment when refuelling.
  • Original Appearance: Helps maintain the factory-style appearance of the fuel flap release control.
  • Reliable Operation: Provides a secure grip for consistent manual operation of the release mechanism.

Symptoms Of Wear Or Failure:
Over time, frequent use, ageing and general wear can cause the original fuel flap release cable knob to deteriorate. Common signs include:

  • Cracked or Broken Knob: Visible cracks, splits or damage may weaken the knob and make it difficult to operate.
  • Loose or Detached Knob: The knob may no longer remain securely attached to the release cable.
  • Difficulty Opening the Fuel Flap: A damaged or loose knob may prevent sufficient pulling force from being applied to the release cable.
  • Worn or Damaged Grip: Surface wear or deterioration can make the knob uncomfortable or difficult to grip.
  • Missing Release Knob: The absence of the knob makes the release cable harder to operate and may leave it exposed to further damage.
  • Poor Appearance: A scratched, faded or damaged knob can detract from the original appearance of the vehicle's interior.

Why Replacement Matters:
  • Replacing a worn or damaged fuel flap release cable knob is an important part of maintaining the convenience, functionality and original appearance of your Porsche.
  • A correctly fitted replacement knob restores a secure operating grip, helping ensure the fuel filler flap can be released smoothly and reliably when refuelling. It also reduces the need to pull directly on the exposed cable, which could contribute to further wear or damage.
  • For classic Porsche owners, replacing deteriorated interior controls helps preserve the vehicle's original appearance and attention to detail.
  • The OE MATCH replacement provides an OE-style solution suitable for routine maintenance, repairs and restoration projects.

Product Information

OE Match fuel flap release cable for Porsche 911 models from 1965–1989, this is the cable operating the fuel filler flap release.

Fits

Porsche 911 1965-69 COUPE F 030 0255>>
Porsche 911 1970-89
Porsche 911 Turbo 1975-89

Check fitment for your specific vehicle (model, year, engine) before ordering.

What This Product Does

The cable provides the mechanical connection used to release the flap covering the fuel filler. Its role concerns access for refuelling, rather than sealing the fuel tank or controlling fuel delivery to the engine. The cap, filler neck and flap hardware perform separate jobs within the surrounding assembly.

Functions

  • Transfers movement through the fuel flap release mechanism.
  • Allows repair of the cable-operated release connection.

Technical Details

  • Brand: OE Match; product reference: 90150431721.
  • Internal diagrams describe this component as a lid-release cable, wire pull or fuel filler flap actuator cable.

Symptoms of Fault

Difficulty opening the filler flap is a reason to inspect the release mechanism. This symptom alone does not establish that the cable needs replacement; the associated flap, hinge and release fittings should also be checked.

Why Replacement Matters

Renewing a defective release cable addresses the mechanical connection needed to open the filler flap. Match the replacement to the vehicle details and applicable chassis notes, and assess the surrounding mechanism before fitting. Replacing this cable does not address faults in the filler cap seal or filler neck.

About Fuel Filler Cap / Neck / Flap

Fuel Filler Cap, Filler Neck & Filler Flap – Precision Fit, Safety, and Style for Porsche Models

Your Porsche’s fuel filler cap, filler neck, and filler flap play a vital role in ensuring a clean, sealed, and secure refuelling system. Together, they prevent fuel evaporation, maintain tank pressure, and protect against contamination, while also adding to the car’s exterior finish and functionality.

At Design911, we supply a comprehensive range of precision-engineered filler components, including fuel caps, filler necks, and flap assemblies designed to deliver perfect fitment, long-lasting durability, and performance-grade sealing. Manufactured from high-quality alloys, polymers, and coatings, these components ensure both safety and reliability in all driving conditions.

Whether you’re restoring a classic Porsche or maintaining a modern model, our manufacturer-quality fuel filler parts ensure secure sealing, corrosion resistance, and an original appearance — down to the last detail.

What Do Fuel Filler Components Do?

Each part of the fuel filler system serves a distinct function that contributes to both performance and safety:

Core Functions:

  • Fuel Filler Cap: Seals the tank to prevent vapour loss, maintain pressure, and stop contaminants from entering.
  • Filler Neck: Guides fuel smoothly from the filler opening into the tank without spillage or backflow.
  • Filler Flap: Protects the filler assembly from dirt, debris, and weather exposure while completing the car’s design.

Together, these parts maintain proper fuel system integrity, vapour control, and aesthetics, ensuring your Porsche performs flawlessly on road or track.

Why Do Fuel Filler Caps, Necks, and Flaps Fail?

Over time, exposure to fuel vapour, moisture, and vibration can wear down even the most durable filler components.

Common Causes of Failure Include:

  • Cracked or worn filler caps, leading to vapour leaks or check-engine lights (EVAP codes).
  • Corrosion or degradation in metal filler necks.
  • Broken hinges or clips on filler flaps.
  • Seal deterioration, causing fuel odours or loss of pressure.
  • Accidental damage from over-tightening or impact during refuelling.

A worn or damaged filler component can compromise fuel system sealing, trigger emissions faults, or simply detract from your Porsche’s aesthetic quality.

Why Replace with Precision-Engineered Fuel Filler Components?

Replacing aged or damaged filler components restores both performance and peace of mind. Our precision-fit filler caps, necks, and flaps are designed to meet or exceed manufacturer specifications for sealing, fit, and durability.

Key Benefits:

  • Restores proper tank sealing and prevents vapour leakage.
  • Eliminates fuel odours and EVAP-related warning lights.
  • Prevents dirt and moisture intrusion into the fuel system.
  • Enhances exterior finish with perfectly matched design and materials.
  • Crafted from corrosion-resistant metals and fuel-safe polymers.
  • Direct-fit replacements for a wide range of Porsche models.

Perfect for restorations, maintenance, or performance upgrades, these components ensure your Porsche retains both its technical integrity and design excellence.

Highlights:

  • High-quality replacement filler caps, necks, and flaps for Porsche models.
  • Precision-engineered sealing and corrosion resistance.
  • Prevents leaks, vapour loss, and fuel contamination.
  • Durable construction for long-term reliability.
  • Direct-fit solutions for air-cooled and modern Porsche vehicles.
  • Restores both performance and authentic visual appeal.
