Diagram ref no 3.
Suitable for replacement where part number 93011060201 or 93011060231 is specified.
The fuel diaphragm damper is fitted within the fuel delivery system and uses an internal diaphragm to absorb pressure pulsations generated as fuel moves through the system.
By damping these fluctuations, it helps maintain smoother and more stable fuel pressure within the fuel rail and associated fuel lines.
What this part does
- Helps damp fuel pressure pulsations
- Supports stable fuel delivery
- Helps smooth pressure variations within the fuel system
- Works with the fuel injection system to maintain consistent operation
- Replaces a worn or faulty fuel diaphragm damper
- Suitable for fuel system repair and refurbishment
- Supplied as an OE Match replacement part
Why Replace This Part?
The internal diaphragm can deteriorate with age, heat exposure and prolonged contact with fuel. A faulty damper may no longer control pressure pulsations effectively and can contribute to fuel system performance issues.
Common reasons for replacement include:
- Fuel system pressure irregularities
- Deterioration of the internal diaphragm
- Fuel leakage around the damper
- Age-related fuel system refurbishment
- Damaged or corroded original component
- Fuel injection system servicing
When to Replace This Part

- Engine Performance: Supports smooth idling and acceleration.
- Fuel System Protection: Dampens pressure fluctuations within the fuel circuit.
- Original Fitment: Maintains factory-correct fuel system specifications.
Why Replace This Part?
Over time, the internal diaphragm can deteriorate due to ageing, continuous fuel pressure and exposure to fuel. A faulty damper may cause excessive fuel pressure fluctuations, rough idling, inconsistent engine performance or fuel leakage.
Replacing a worn or damaged damper with a genuine Porsche component helps restore effective pressure damping, reliable fuel delivery and the original performance of the fuel injection system.
When to Replace This Part?
- Fuel Pressure Fluctuations: Excessive pressure pulsations detected during testing.
- Rough Idling: Uneven engine running associated with fuel pressure instability.
- Poor Acceleration: Hesitation or inconsistent engine response.
- Fuel Leaks: Visible leakage or fuel odour around the damper.
- Fuel System Repairs: During maintenance when the original damper is found defective.
Where Does It Fit on the Car?
Location: Engine compartment – fuel injection system.
The fuel diaphragm damper is fitted within the engine's fuel delivery system, connected to the fuel rail assembly towards the rear of the engine.
It works alongside the fuel pressure regulator, fuel rails and injectors to reduce pressure pulsations and support consistent fuel delivery.
