What This Product Does
 This kit brings together the tandem and scavenge oil pumps used to move and return engine oil within the lubrication system. The pumps help maintain oil circulation around critical engine components and return oil from scavenge areas back to the main oil circuit for consistent lubrication.

Functions
Circulates engine oil through internal galleries and componentsScavenges oil from designated areas and returns it to the main oil supplyHelps maintain stable oil pressure within the systemSupports correct lubrication of bearings and other moving parts

Symptoms of Fault
Low or fluctuating oil pressure readingsWarning messages or lamps related to oil pressure (model dependent)Increased mechanical noise from the engine, especially when hotSigns of oil aeration or poor return flow in the lubrication system

Why Replacement Matters
Oil pumps are central to the engine’s lubrication system. When wear or internal damage reduces their ability to move oil or hold pressure, the risk of accelerated internal wear increases. During major engine work or a rebuild, these pumps are often renewed together so the scavenge and pressure circuits remain matched in condition. Using a dedicated kit helps ensure the correct parts are combined for the intended Porsche applications and reduces the chance of mixing incompatible components.

Product Information
Product Information
Brake Pump Vacuum Line.

The Porsche Brake Pump Vacuum Line 99711005503 is a genuine replacement vacuum pipe for the brake-assistance system on Porsche 997.1 models.

Fits:

  • Porsche 997 MK1 Carrera 2 3.6L 2005-08
  • Porsche 997 MK1 Carrera 2S 3.8L 2005-08
  • Porsche 997 MK1 Carrera 4 3.6L 2005-08
  • Porsche 997 MK1 Carrera 4S 3.8L 2005-08  

Diagram Ref No 38

The line carries vacuum from the engine-driven vacuum/tandem pump into the brake booster circuit. This vacuum allows the brake servo to provide power assistance when the brake pedal is pressed, reducing the amount of physical pedal force required from the driver.

Designed to follow the original Porsche routing and connection arrangement, this replacement is suitable for renewing an original line that has become cracked, brittle, damaged or unable to maintain a reliable vacuum seal.

What This Product Does:

The hydraulic braking system provides the actual braking force, while the brake booster uses vacuum to reduce the effort required at the brake pedal.

The vacuum pump generates the required vacuum, and this line transfers it to the brake-assistance system.

Its main functions include:

  • Carrying vacuum from the vacuum/tandem pump
  • Supplying the brake booster system with vacuum
  • Maintaining a sealed vacuum circuit
  • Supporting consistent power-assisted braking
  • Reducing brake pedal effort
  • Maintaining the correct factory vacuum-line routing
  • Providing secure connections between the vacuum pump and brake-assistance system

The line does not create braking pressure itself. Instead, it enables the brake booster to assist the hydraulic braking system.

Symptoms Of Wear Or Failure:
Age, engine-bay heat and vibration can cause the original vacuum line and its connections to deteriorate. Cracking has been documented particularly around the transition between the metal pipe and flexible hose section.

Common symptoms may include:

  • Brake pedal becoming unusually hard
  • Increased effort required when braking
  • Reduced brake servo assistance
  • Inconsistent power-assisted braking
  • Pedal becoming harder after repeated brake applications
  • Hissing or vacuum-leak noises
  • Visible cracks in the vacuum hose
  • Splitting near hose-to-pipe connections
  • Brittle or hardened hose material
  • Loose or damaged vacuum connections
  • Damaged retaining clips
  • Line becoming detached or incorrectly supported
  • Poor vacuum retention within the brake-assistance circuit

A hard brake pedal can also be caused by a faulty brake booster, vacuum pump, check valve or another vacuum-system component, so correct diagnosis is recommended.

Why Replacement Matters:
The brake booster relies on an adequate vacuum supply to provide normal power assistance.

If the vacuum line cracks or leaks, the available vacuum can fall and brake assistance may be reduced. The hydraulic braking system may still operate, but considerably more pedal force may be required to achieve the same braking effect.

This can make the vehicle more difficult to brake comfortably and predictably, particularly during repeated braking or situations requiring rapid deceleration.

Replacing a damaged vacuum line helps restore:

  • Correct vacuum supply to the brake-assistance system
  • Normal brake pedal assistance
  • Consistent pedal effort
  • Reliable brake servo operation
  • Proper sealing of the vacuum circuit
  • Correct factory hose routing and mounting

Because this component supports the braking assistance system, visible cracking, damaged connections or vacuum leakage should be addressed promptly.

About Oil Pumps & Gaskets

Engine Oil Pumps & Gaskets – Essential Components for Porsche Lubrication Systems

The engine oil pump is the heart of your Porsche’s lubrication system. It maintains the correct oil pressure and flow throughout the engine, ensuring that every moving component receives consistent lubrication for smooth operation and long-term durability. Paired with precision-engineered oil pump gaskets, these components prevent leaks and maintain pressure integrity — critical for performance and reliability.

At Design911, we stock a wide range of high-quality engine oil pumps and sealing gaskets designed for Porsche engines across all generations. Constructed from heat-resistant alloys and advanced sealing materials, these parts are built to deliver dependable oil circulation under demanding road and track conditions. Whether you’re performing a complete rebuild or servicing your engine, our manufacturer-quality oil pumps and gaskets ensure flawless performance and long-term protection.

What Do Engine Oil Pumps & Gaskets Do?

The oil pump works continuously to circulate engine oil, maintaining consistent pressure across all internal systems. The accompanying gaskets ensure that no oil escapes during this process.

Core Functions:

  • Circulate and pressurise oil to protect internal engine components.
  • Prevent metal-on-metal contact, reducing friction and wear.

  • Seal the pump and associated components to prevent oil leaks.
  • Support temperature regulation through stable oil flow.

Together, oil pumps and gaskets are the backbone of your engine’s lubrication and cooling efficiency.

Why Do Oil Pumps & Gaskets Fail?

Over time, wear, contamination, and heat cycles can compromise the performance of both the oil pump and its seals.

Common Causes of Failure Include:

  • Internal wear of pump gears or rotors from oil contamination.
  • Loss of pressure due to clogged oil passages or relief valve faults.
  • Gasket hardening or cracking from prolonged heat exposure.
  • Oil leaks caused by worn seals or improper installation.
  • Low oil levels or infrequent maintenance, accelerating wear.

Symptoms of failure may include low oil pressure warnings, unusual engine noise, overheating, or oil leaks, all of which indicate the need for inspection and replacement.
