My gas cap on Stang is so loose I think it will fall off on her maiden voyage. How do I "tighten" it up? Can the gasket type material be replaced? It looks like that would help. Any ideas? And no, "Righty tighty" is not what I am looking for.
All that grips it is the pressure against the inside of the filler neck. If you carefully bend the lip inward, the tabs on the cap should grab better. A new gasket will also help take up some of the slack.
