Diagram ref. 11

It is designed as the fuel line running from the fuel rail to the diaphragm damper on selected Porsche 924S and 944 models. This part is used in the fuel injection system and connects key fuel delivery components in the engine bay.

This part cross-references with earlier Porsche number: 94411041302

Functions
• Connects the fuel rail to the diaphragm damper
• Carries fuel within the engine fuel injection system
• Helps maintain correct fuel delivery to the fuel rail system
• Supports proper fuel pressure damping and fuel system stability
• Provides a factory-correct fuel line route and connection
• Helps reduce fuel pulsation when used with the correct diaphragm damper
• Replaces an aged, cracked, leaking or damaged original fuel line
• Maintains OE Porsche fitment and fuel system specification.

Why Replace This Part?
Fuel lines are exposed to fuel pressure, engine-bay heat, vibration and age-related deterioration. Over time, the original line can harden, crack, seep fuel or deteriorate at the fittings. Because this line carries fuel in the engine bay, any sign of leakage or fuel smell should be inspected immediately. Replacing the old line with a Genuine Porsche OE fuel line helps restore the correct connection between the fuel rail and diaphragm damper, supporting safe fuel delivery and original Porsche fuel system reliability.

When to Replace This Part
•  If there is a fuel smell in the engine bay
•  If the line is cracked, brittle, swollen or visibly damaged
•  If fuel is seeping or leaking from the hose or fittings
•  During fuel rail, diaphragm damper or fuel pressure system repairs
•  During fuel injection system restoration or preventative maintenance
•  If fittings are corroded, seized or damaged
•  When replacing old, non-original or incorrectly routed fuel hose
•  Before recommissioning a stored Porsche 924S or 944.

Where It Fits on the Car
This fuel line fits in the engine bay fuel injection system, running between the fuel rail and the diaphragm damper. It is shown in Porsche fuel injection / collection rail diagrams and is commonly identified as the fuel line from the fuel rail to the diaphragm damper.

Porsche 944 Turbo S 2.5L 1988 

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.
