Chevrolet S10 gas tank leaking during refueling despite filler neck replacement on Chevrolet S10

Some Chevrolet S10 owners report experiencing gas tank leaks during refueling, even after replacing the filler neck. These leaks can occur due to overfilling the tank, which may cause the vent tube to spill fuel when it exceeds capacity. Additionally, some owners find that damage to the tank from external impacts can lead to small leaks that are not resolved by simply replacing the filler neck. Cracked gas tanks near the filler neck attachment have also been reported as a cause of leaks, despite previous repairs. Furthermore, faulty seals or connections around the filler neck or tank may contribute to the problem, necessitating further inspection and repair. A thorough examination of the fuel system is recommended for those experiencing persistent gas tank leaks.
