The engine relies on a continuous and stable fuel supply during starting, idling, acceleration and higher-load driving. If the pump can no longer deliver the required amount of fuel, the engine may become difficult to start, hesitate under acceleration, lose power or stop running altogether.
What This Product Does:
- Transfers fuel from the fuel tank toward the engine.
- Provides the fuel flow required for normal engine operation.
- Helps maintain the required fuel-system pressure for the intended application.
- Supports reliable cold and warm starting.
- Provides fuel during idle, cruising and acceleration.
- Helps maintain consistent engine performance as fuel demand increases.
- Supports correct operation of the vehicle's fuel delivery system.
- Helps prevent fuel starvation caused by inadequate pump output.
- Replaces a worn, damaged, noisy or failed fuel pump.
- Provides an OE-style replacement for compatible Porsche applications.
Symptoms Of Wear Or Failure:
- Difficulty starting the engine.
- Extended cranking before the engine starts.
- Engine failing to start despite fuel being present.
- Intermittent starting problems.
- Engine hesitation during acceleration.
- Loss of power under load.
- Poor performance at higher engine speeds.
- Engine cutting out unexpectedly.
- Intermittent stalling.
- Fuel starvation symptoms.
- Unusual buzzing, whining or other noises from the fuel pump.
- Fuel pressure or flow below specification.
- Intermittent pump operation.
- Visible fuel leakage around the pump or connections.
- Electrical testing confirming that the pump is receiving the correct supply but is not operating properly.
Why Replacement Matters:
- The engine cannot operate correctly without a reliable fuel supply. A weakening fuel pump may provide enough fuel for starting or low-speed operation but struggle to meet demand during acceleration or higher engine loads.
- Insufficient fuel delivery can cause hesitation, poor acceleration, loss of power and stalling. Intermittent pump failure can be particularly troublesome because the vehicle may operate normally at times before unexpectedly cutting out or refusing to restart.
- A complete fuel pump failure can leave the vehicle unable to start or run, potentially resulting in an unexpected breakdown.
- Fuel leakage is even more important to address immediately. Petrol is highly flammable, and any leakage around the pump, hoses or connections can create a serious fire hazard.

Diagram ref no 30
This rubber mount cushions the fuel pump, reducing vibration and noise while helping keep the pump securely in place during operation. It also protects adjacent components from mechanical stress caused by engine vibration and motion.
Over time, rubber buffers can harden, crack, or deteriorate from heat and age, leading to excessive vibration, noise, and potential stress on the fuel pump assembly. Replacing worn mounts with OE-match buffers ensures the fuel pump remains secure and smooth-running, preserving the integrity and reliability of the fuel delivery system.
When to replace:
• Rubber buffer shows cracks, splits, or hardening
• Noticeable vibration or noise from the fuel pump area
• Fuel pump feels loose or poorly supported
• During fuel system servicing or restoration
• As part of routine preventive maintenance

The rubber mount supports the fuel pump in its mounting position and helps absorb vibration generated by pump operation and vehicle movement. It keeps the pump correctly located, reduces noise, and helps protect the fuel pump and mounting bracket from excess stress.
Functions
• Secures the rear fuel pump to its mounting bracket
• Helps isolate fuel pump vibration from the body
• Reduces fuel pump noise and resonance
• Supports correct pump alignment and fitment
• Helps protect fuel lines and pump fittings from movement stress
• Replaces perished, cracked, loose, or missing original rubber mounts
• OE Match replacement for fuel system repair or restoration.
Why Replace This Part?
Rubber fuel pump mounts can harden, crack, split, collapse, or detach with age, fuel exposure, heat, and road vibration. A worn mount may allow the fuel pump to move, vibrate, or create extra noise, and can place stress on fuel lines and electrical connections. Replacing the mount helps restore secure fuel pump installation and quieter, more reliable operation.
When to Replace This Part
• The fuel pump mount is cracked, perished, split, or missing
• The fuel pump feels loose or moves on its bracket
• There is increased fuel pump noise or vibration
• The rear fuel pump or fuel lines are being replaced
• The mounting hardware has been removed during fuel system service
• Fuel pump alignment or bracket security needs to be restored
• The vehicle is undergoing classic Porsche fuel system restoration.
Where it fits on the car
This rubber mount fits at the rear fuel pump mounting point, securing the fuel pump to its bracket or body mounting area. It forms part of the fuel pump support assembly on Porsche 911 models using a rear-mounted fuel pump arrangement.
