Designed for the fuel filler neck assembly, this flange provides a mounting and connection point within the original fuel filling arrangement.

Over time, original components can become corroded, distorted or damaged, making replacement important during fuel system repairs or classic Porsche restoration.

What Does It Do?

The fuel filler neck flange forms part of the connection between the filler neck and its associated mounting components, helping maintain a secure and correctly positioned fuel filling assembly.

Why Does It Fail?

Common causes include:

• Corrosion and moisture exposure
• Age-related deterioration
• Damage during fuel tank removal
• Distortion from previous repairs
• General wear over time

When Should It Be Replaced?

Replace the flange if it becomes corroded, cracked, distorted or damaged.

Replacement is also recommended during fuel tank refurbishment or when restoring the original fuel filler assembly.

Checks & Diagnosis

Inspect the flange for corrosion, damage and loose mounting points. Check the surrounding filler neck, connections and seals for deterioration or signs of fuel leakage.

Installation Notes

Inspect the surrounding fuel filler components before installation. Ensure the flange is securely fitted and all associated seals and connections are in good condition.

Check for fuel leaks before returning the vehicle to service.
