Aston & Monza Locking Fuel Caps
We offer two styles of locking fuel cap sets, Aston & Monza, both made from polished alloy. The Aston & Monza locking fuel cap sets include a fuel cap cover and fuel cap as a complete kit. The kits bolt directly onto the tank filler neck. These caps are vented and will fit most BMC type filler necks as found on MG's.

Alternatively, you can use an Aston cap cover and fit with one of our compatible locking fuel caps, (Part No’s: GSS154 – Vented or WLD100310 - non-vented) or they can be used with an existing standard cap. They will fit over the standard cap and bolt directly to the tank filler neck.

To fit any of these caps you will need to change the filler neck extension to 470-852.

Note: When fitting, position the fuel cap carefully to allow for over riders and other components of the car, allow sufficient room for the flap to clear when refuelling.
