The Aston cap covers are designed to 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 to an MGA 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.
