Information
Fuel Tank Cap Seal.
Maintain a secure, leak-free seal for your Porsche's fuel system with this OE Match Fuel Tank Cap Seal, manufactured as a direct replacement. Produced to OE-style specifications, this rubber sealing ring fits between the fuel filler cap and filler neck, helping to prevent fuel vapours, moisture, and contaminants from entering or escaping the fuel tank while ensuring the cap seals correctly.
Fits:
Diagram Ref No 4
Over time, the original seal can become hardened, flattened, cracked, or perished through exposure to fuel, heat, and age. A deteriorated seal may reduce the effectiveness of the fuel cap, potentially allowing fuel odours, moisture ingress, or vapour leaks. Replacing the fuel tank cap seal restores the correct sealing performance and helps maintain the integrity of the fuel system. This OE Match component is ideal for routine maintenance, fuel system repairs, and Porsche restoration projects.

What This Product Does:
- Creates a secure seal between the fuel cap and filler neck.

Symptoms Of Wear Or Failure:
- Cracked, split, or perished rubber seal.
- Flattened or compressed sealing surface.

- Fuel cap no longer sealing securely.
- Signs of moisture or contamination around the filler neck.
- Visible deterioration caused by age or fuel exposure.

- Evidence of vapour leakage around the fuel filler.
Why Replacement Matters:
- The fuel tank cap seal plays a vital role in maintaining the integrity of the fuel system by creating a tight seal between the fuel cap and the filler neck.

- Replacing the seal restores the correct sealing performance, helping to protect the fuel system, reduce fuel odours, and maintain reliable operation. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match fuel tank cap seal provides the correct fit, dependable quality, and long-lasting durability, making it an excellent choice for Porsche maintenance, fuel system repairs, and restoration projects.
