T4 Fuel Cap (Bayonet Style)

This Replacement Locking Fuel Cap is designed to fit all Volkswagen Transporter T4 models equipped with the bayonet-style filler neck. Manufactured to OEM standards, this cap provides a secure seal to prevent fuel evaporation and contamination, while also offering theft protection with its integrated lock mechanism.

Supplied complete with two keys, the locking mechanism ensures your fuel system stays secure, especially on camper conversions or work vans often left unattended. The cap uses a bayonet fitting, meaning it twists and locks securely into place with a firm quarter turn, maintaining proper pressure and preventing leaks.

Please note that some T4 models were fitted with a screw-type cap — check your existing filler neck style before ordering to ensure compatibility.
