- Visible deterioration caused by age or fuel exposure.
- Loose-fitting fuel cap despite being correctly tightened.
- 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. A worn or deteriorated seal can allow fuel vapours to escape, permit contaminants or moisture to enter the fuel tank, and reduce the effectiveness of the fuel cap.
- 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.

The OE Match fuel tank lid for Porsche 356 / 356A / 356B T5 closes the fuel filler opening and works with the associated sealing ring. It provides a replacement option when the existing lid is missing, damaged or no longer seats correctly.
Fits:
- Porsche 356 A/540.1 1950–1959
- Porsche 356B 1959–63
- Porsche 356 B-T5 1959–1965

Check fitment for your specific vehicle (model, year, engine) before ordering. Confirm the filler arrangement, particularly the T5 qualification on 356B applications.
What Is This Part?
This is the removable lid used to close the fuel tank's filling opening. It forms part of the tank assembly alongside the sealing ring and breather components. The lid must sit correctly against its sealing surface so that the lid and ring can close the opening together. During fuel tank maintenance or restoration, inspect both the lid and the surrounding filler area rather than assuming that a sealing problem requires replacement of the tank itself.
What Does This Part Do?
- Closes the filler opening: Covers the opening after refuelling.
- Works with the sealing ring: Provides the closing surface against which the associated ring seals.
- Allows refuelling access: Can be removed to access the tank's filling opening and refitted afterwards.
- Covers the tank entrance: Helps keep dirt and moisture away from the opening when correctly fitted.
Why Replace This Part?
A damaged or distorted lid may not sit evenly against the filler opening. Wear at its retaining features can also prevent it from fastening correctly. Replacement is appropriate where inspection confirms that the lid itself is damaged, excessively worn or missing.
Check the sealing ring and filler seating surface at the same time. A hardened, split or displaced ring can cause poor sealing even when the lid remains serviceable. Fuel odours or staining warrant inspection of the surrounding tank connections and breather components as well; they do not identify the lid as the cause on their own.
When to Replace This Part?
- Visible damage: The lid is cracked, bent or distorted.
- Poor seating: It sits unevenly after the sealing ring and filler surface have been checked.
- Worn retention: It will not fasten securely because its retaining features are damaged.
- Surface deterioration: Corrosion or damage affects the lid's sealing contact area.
- Missing or unsuitable lid: The existing closure is absent or does not match the vehicle's filler arrangement.
Where Is This Part Fitted?
Location: At the fuel tank filler opening, where it closes against the associated sealing ring. Match the lid to the vehicle's existing tank and filler arrangement before fitting.
