National Parts Depot sells a thin rubber gasket to replace the cracked old rubber gaskets in this type gas cap.
Good news, they're only a dollar.
Bad news, they warp after a couple of months exposed to ethanol fumes.

''Gasket, Fuel Cap. Repro
65, 73 Mustang.'' *
While they're still good, you'll get a whoosh of vapor popping out when you open the cap. No more wet wingtips.

* Ford application cited I know, but in this period there was a lot of commonality with all Detroit brands.
