Can you overfill a fuel tank?
Overfilling the gas tank can cause liquid gas to enter the charcoal canister, or carbon filter, which is designed only for vapor. “When we overfill the tank, it sends all of the excessive fuel to the evaporation/charcoal canister and kills the life of that canister,” Carruso says.
