• 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.
