Fuel Pumps

Restore reliable fuel delivery and consistent engine performance with these OE Match Fuel Pumps. Designed for compatible Porsche applications, the fuel pump is a critical part of the vehicle's fuel-delivery system, supplying fuel from the tank towards the engine at the pressure and flow required by the fuel system.

Fits:

• Porsche 955 Cayenne 3.2L V6 2003-06
• Porsche 955 Cayenne S 4.5L V8 2003-06
• Porsche 955 Cayenne Turbo 4.5L 2003-06
• Porsche 955 Cayenne Turbo S 4.5L 2006>>
• Porsche 957 Cayenne 3.6L 2007-10
• Porsche 957 Cayenne S / GTS 4.8L 2007-10
• Porsche 957 Cayenne Turbo / Turbo S 4.8L 2007-10  

Modern fuel-injected engines depend on a stable and continuous fuel supply. The pump operates electrically and must provide sufficient fuel volume across a wide range of operating conditions, from starting and idling through to acceleration and high engine loads.

Fuel pumps operate whenever the engine requires fuel and are exposed to continuous electrical and mechanical loads. Over time, the internal electric motor, pumping mechanism, electrical connections or associated components can deteriorate. Contamination within the fuel tank can also contribute to premature wear.

A weak or failing pump may still operate but be unable to maintain adequate fuel delivery when demand increases. This can cause difficult starting, hesitation, loss of power or engine-management faults.

These OE Match Fuel Pumps provide high-quality replacement options for failed, noisy or underperforming original fuel pumps.

What This Product Does:

• Draws fuel from the vehicle's fuel tank.
• Supplies fuel towards the engine's fuel system.
• Provides the flow required for reliable engine operation.
• Helps maintain the required fuel supply pressure.
• Supports dependable engine starting.
• Supplies sufficient fuel during acceleration and increased engine load.
• Helps maintain smooth and consistent engine performance.
• Supports correct fuel-injection operation.
• Works with the fuel lines, filters, pressure-control components and injection system.
• Helps maintain consistent fuel delivery across different driving conditions.
• Replaces a weak, noisy, intermittent or completely failed fuel pump.
• Provides an OE Match replacement for compatible Porsche applications.  

• Engine cranks but does not start.
• Extended cranking before the engine starts.
• Intermittent starting problems.
• Engine suddenly failing to start.
• Hesitation during acceleration.
• Loss of power under heavy load.
• Poor high-speed performance.
• Engine stumbling or cutting out.
• Intermittent engine stalling.
• Rough or inconsistent engine operation.
• Fuel-pressure-related diagnostic fault codes.
• Lean-running fault codes.
• Fuel pressure below specification.
• Engine-management warning light.
• Unusually loud humming or whining from the fuel tank.
• Pump operating intermittently.
• Vehicle starting when cold but developing problems when warm.
• Fuel delivery failing during periods of high demand.  

• The engine requires a continuous and correctly regulated supply of fuel to operate properly. If the fuel pump cannot provide sufficient flow, the engine may receive less fuel than required, particularly during acceleration or high-load operation.
• A pump in the early stages of failure may provide enough fuel for idling or gentle driving but struggle when demand increases. This can result in hesitation, reduced performance or intermittent loss of power.
• As deterioration progresses, starting may become increasingly difficult until the pump eventually stops operating altogether.
• Insufficient fuel delivery can also cause the engine to operate lean under certain conditions. The engine-management system may detect the problem and record fuel-pressure or mixture-related faults.
• Replacing a confirmed faulty pump with the correct OE Match Fuel Pump helps restore reliable fuel delivery, consistent starting and dependable engine performance.
