Restore a leak-free seal on your 1979-1998 Mustang's fuel system with this direct-replacement fuel sending unit O-ring gasket from All Classic Parts. The factory rubber compound degrades over time, leaving you with fuel odors, seepage around the tank opening, and a sending unit that no longer seats properly. Swapping in a fresh gasket corrects the problem at the source.
Seals the tank opening correctly. The 2-7/8-inch diameter O-ring installs under the fuel sending unit mounting surface and compresses against the tank to form a complete seal. No adhesives or sealants are needed; the gasket does the work on its own.
Built to handle a demanding environment. The synthetic rubber blend resists heat, oil, and fuel-system chemicals, so the material stays pliable and maintains its sealing pressure instead of cracking or shrinking the way aged OEM rubber does.
A straightforward fix that restores original functionality. Whether the existing gasket has hardened, torn, or simply reached the end of its service life, this replacement brings the sending unit back to factory-correct sealing performance without modifications to the tank or sending unit hardware.
