I was refueling my van and gas started pouring out from the bottom. After looking I discovered the fuel filler neck was rusted thru. The van only has 64k miles. I replaced it myself at this time. There was no collision damage. . . . Simply heavy corrosion.
Gas filler tube rusted through and gasoline leaked every time I refueled. This was not a small hole. The metal on the whole tube broke down causing fuel to leak and creating a fire hazard.
