Is this normal? i might of overfilled it and maybe it has a valve that controls the fuel capacity? im hoping its that but did i harm anything? it leaked a bit from the bottom somewhere behind the bumper. any help is appreciated
It's not normal but it's very common on mustangs. Your goons have to replace your fill tube that runs from the gas tank to the fill hole. It happened on one of mine and 2 of my buddies. Maybe yours is just loose, so get under there and check it out.
