Return fuel line in centre tunnel. 
This is an original Porsche metal fuel line routed through the centre tunnel of early 911/912 models. It carries fuel or return flow as part of the vehicle’s original fuel-system layout.

Fits:
Porsche 911 E / 911S - 1969 to to 1971 (2 required per car)
Porsche 911T 1969 to 1969 (1 required per car)

Diagram ref no 25 (for 911T, 911) / 18 (for 911E/S)

Runs from the fuel tank area through the centre tunnel; often termed a “control line” or “return line.”

With age the original metal line can suffer from corrosion, fatigue or damage - leading to fuel leaks or vapour loss, which pose safety risks. Installing the correct genuine Porsche line ensures the system maintains its original routing, integrity and reliable fuel delivery.

Return fuel line in centre tunnel. 
Metal fuel line that runs the length of the centre tunnel.

Fits:
Porsche 911 E / 911S - 1969 to to 1971 (2 required per car)
Porsche 911T 1969 to 1969 (1 required per car)
Porsche 911 - 1972 to 1973 (1 required per car)

Diagram ref no 25 (for 911T, 911) / 18 (for 911E/S)

This metal fuel line provides reliable fuel-circuiting within the vehicle’s structure, directing fuel return or feed through the centre tunnel. It must maintain integrity under fuel pressure, vibration and heat, while resisting corrosion for long service life.

Over time, the original fuel lines in the centre tunnel can deteriorate due to vibration, fuel exposure, and age. This can lead to leaks, vapour loss, or safety risks. Replace the fuel line when:
 • Corrosion or rust is visible on the metal surface.
 • You notice fuel odour or damp spots near the tunnel area.
 • The line shows signs of wear, cracking, or deformation.
 • Performing a full restoration, engine rebuild, or fuel-system refresh.

Installing a high-quality new fuel line ensures proper routing, durable materials, and leak-free operation - restoring the safety and reliability of your Porsche’s fuel system.
