Why Replace This Part?
Fuel return lines can deteriorate over time due to fuel exposure, age, heat, pressure and corrosion. A worn or damaged return line may leak, smell of fuel, corrode at the fittings or become unsafe for continued use. Replacing the line with a Genuine Porsche OE fuel return line helps restore the correct factory fuel system layout and supports safe, reliable fuel return operation. Any fuel leak or fuel smell should be inspected immediately, as fuel system faults can create a serious safety risk.

•   During fuel pump, fuel filter or fuel accumulator service where related lines are removed
•   When replacing old, non-original or incorrectly routed fuel pipework
•   Before recommissioning a car that has been stored for a long period.
