Replacement gas tank filler neck grommet designed for 1970-1972 Ford truck models using the 25-gallon auxiliary under-cab gas tank. This molded rubber grommet seals the filler neck where it passes through the tank or mounting bracket, preventing fuel leaks, road debris intrusion, and excess vibration. Engineered for durability and a precise OEM-style fit, it restores a secure, weatherproof connection between the filler neck and tank assembly. Ideal for restoration projects or routine maintenance, the grommet extends service life and helps maintain fuel system integrity with a simple, reliable part.
