This OE Match Fuel Tank Cap (Plastic Type) is a high-quality replacement component designed to match original Porsche specifications. Installed on the fuel filler neck, this cap provides a secure closure to the fuel system, maintaining proper pressure and preventing fuel vapour escape on Porsche 911 models.
Fits:
Porsche 911 1978 - 1989
Designed specifically for late air-cooled Porsche 911 models, this plastic-type cap offers a lightweight and reliable alternative to older metal versions, while retaining correct fitment and functionality. It is an essential component for both routine maintenance and restoration work.
This fuel tank cap seals the fuel system, preventing leaks and vapour loss while protecting the tank from external contamination.
Function
• Provides a secure seal for the fuel filler neck
• Prevents fuel vapour escape and leaks
• Protects against dirt, moisture, and contaminants
• Helps maintain correct fuel system pressure
• Ensures safe and reliable fuel system operation
A worn or faulty fuel cap can lead to fuel vapour leaks, reduced fuel efficiency, and contamination of the fuel system. Over time, seals within the cap can degrade, compromising its ability to maintain proper pressure. Replacing the cap ensures safe sealing, protects the fuel system, and maintains optimal vehicle performance.
When to replace
• Cap no longer seals tightly
• Visible cracks or wear in plastic housing
• Signs of fuel smell or vapour leakage
• Seal appears damaged or hardened
• During fuel system maintenance or restoration

This lockable cap includes two keys for secure sealing of the tank, offering a direct-fit solution that matches the original Porsche design in shape, materials and function. It ensures proper fitment, reliable locking functionality and guards against fuel theft or contamination.
Fits:
Porsche 944 1982 - 1991
Porsche 964 1989 - 1994
Porsche 986 Boxster 1997 - 2004
• Position on Vehicle: Wind the cap onto the fuel-filler neck until secure lock-engagement; remains accessible at the exterior fuel door.
• Applications: Ideal when original tank cap is missing, damaged, ill-sealing, key lost or when installing a new fuel system component and you require a correct-fit lockable cap.
A properly fitting and locking fuel tank cap is essential for maintaining fuel system pressure, preventing vapour loss, deterring contamination, and ensuring the correct appearance of the filler area. A damaged or missing cap can lead to fuel odours, tank venting issues, or water/dirt ingress. Replacing a cap restores optimal function and peace of mind.
When and why to replace:
• Cap is cracked, key lost or damaged, locking mechanism faulty.
• Fuel vapour smell coming from filler area or tank not sealing properly.
• During tank servicing or filler-neck replacement when original cap is removed.
• For restoration where correct appearance, finish and operation of the fuel filler area are important.
