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.
