Why does Fuel leak when filling tank of 2004 Mitsubishi endeavor?

Fuel may leak when filling the tank of a 2004 Mitsubishi Endeavor due to a faulty or damaged fuel filler neck, which can allow gasoline to escape during filling. Additionally, a malfunctioning venting system, such as a clogged or broken vapor canister, can cause pressure buildup and result in fuel spillage. It's also possible that the fuel tank itself has cracks or holes. Regular inspection of these components can help prevent leaks.
