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.

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.
