Fuel Filler Neck Replacement FAQ

Common questions about fuel filler necks, replacement, and our parts

A fuel filler neck is the metal or plastic tube that connects your gas cap to the fuel tank. It's the part you insert the gas pump nozzle into when fueling. Over time, filler necks rust, crack, or corrode — especially in northern states where road salt is used. A damaged filler neck can cause fuel leaks, failed emissions inspections, check engine lights, and strong gas smells. Replacing it restores safe fueling and eliminates leak risks.
