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.
