Gas caps are an often overlooked but important part of your Mustang’s fuel system. Mustang gas caps create a seal that prevents fuel leakages out of the tank and stops dirt and grime from getting in the tank. Over time, repeated opening and closing can cause gas caps to become worn out and no longer provide an airtight seal.

We offer a wide selection of replacement gas caps in pop open or twist off style, with finishes like shiny black or chrome, and emblem, logo and billeting options. Gas caps are available for Mustang model years 1965-2022, giving you options for every generation. We even offer a locking gas cap with keys for added security. Plus, we have gaskets, bumpers, and any other hardware you'll need for a successful installation. Continue to make sure your fuel systems are protected with a new fuel tank and filler pipes.
