Diagram ref. 11
The fuel line connects the fuel rail to the diaphragm damper within the fuel injection system. The diaphragm damper helps smooth pressure pulses in the fuel circuit, while the line carries fuel securely between the connected components to support stable fuel pressure and consistent engine running.
This part cross-references with earlier Porsche number: 94411041302
Functions
• Connects the fuel rail to the diaphragm damper
• Carries fuel through the injection system
• Supports stable fuel pressure delivery
• Helps reduce fuel pressure pulsation through the damper circuit
• Replaces aged, leaking, cracked, or damaged original fuel lines
• Helps restore safe fuel system sealing
• OE Match replacement for Porsche fuel system repair or restoration.
Why Replace This Part?
Fuel lines can deteriorate over time due to fuel exposure, heat, pressure, vibration, and age. The hose or pipework can crack, harden, seep, corrode, or leak, while fittings may become worn or seized. A damaged fuel line can cause fuel smell, fuel pressure loss, poor running, starting issues, or unsafe fuel leakage. Replacing the line helps restore fuel system safety, correct fuel pressure control, and reliable engine performance.
When to Replace This Part
• The fuel line is cracked, leaking, perished, corroded, or damaged
• Fuel smell or seepage is present in the engine bay
• The fittings or unions are worn, seized, or heavily corroded
• Fuel pressure instability or poor running is suspected
• The fuel rail or diaphragm damper is being replaced
• The fuel injection system is being serviced or recommissioned
• The vehicle is undergoing Porsche 924S or 944 fuel system restoration.
Where it fits on the car
This fuel line fits within the engine bay fuel injection pipework, connecting the fuel rail to the diaphragm damper. It forms part of the fuel pressure control circuit and should be installed according to the factory fuel system routing.

OEMatch Pressure Valves / Sensors / Dampers / Regulators — Fit, Function, Confidence
OEMatch supplies a focused selection of pressure valves, sensors, dampers and regulators for Porsche models. These fuel system parts control rail pressure, smooth pulsations and provide the inputs the engine management system needs to keep fuel delivery and throttle response consistent across load and temperature ranges.
Available Types
- Fuel pressure regulator (mechanical and vacuum-controlled)
- Fuel rail pressure sensor
- Fuel damper and accumulator
- Pressure relief and pressure-limiting valves
Understanding OEMatch Pressure Valves / Sensors / Dampers / Regulators
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original pressure valves, sensors, dampers and regulators.
OE (Original Equipment) refers to parts matching original specifications for the pressure valves, sensors, dampers and regulators and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM pressure valves, sensors, dampers and regulators engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Fuel pressure regulators, sensors and dampers work together to maintain the correct pressure in the fuel rail, to smooth transient pulses from the pump and injectors, and to report pressure to the engine control unit. Regulators adjust flow to match demand, sensors provide feedback for closed-loop control, and dampers reduce pressure spikes that can affect injector timing and pump life.
Benefits Include
- Restores stable fuel pressure for consistent combustion and throttle response
- Reduces pressure fluctuations that can accelerate wear on pumps and injectors
- Helps maintain fuel metering accuracy for smoother running
Why Pressure Valves / Sensors / Dampers / Regulators Wear and Fail
- Contamination and clogging from dirty or degraded fuel
- Diaphragm or internal seal deterioration due to age and heat
- Corrosion from moisture or ethanol-containing fuels and electrical faults in sensors
The Importance of Replacing with OEMatch Pressure Valves / Sensors / Dampers / Regulators
Replacing worn or faulty units restores accurate pressure regulation and sensor feedback, which supports drivability and can prevent secondary damage to fuel pumps or injectors. OEMatch parts are supplied alongside comprehensive cross-reference data to help identify the correct component for each Porsche model and application.
Advantages
- Range selected for Porsche applications, including fuel pressure regulators, dampers and sensors
- Catalogued cross-references and wide part coverage to aid correct identification; OEMatch has catalogue records covering thousands of part numbers and many OE cross-references
- Components finished in corrosion-resistant materials and with electrical connectors matched to factory interfaces where applicable
Support & Advice
Fitting can appear straightforward but may require procedures such as correct torque settings and careful routing of hoses. If you lack the correct tools or model-specific knowledge, we recommend professional installation. Recheck fasteners and connections after initial running and observe for any diagnostic codes or fuel odours.
