when i try to pump gas it just runs back out down side of car, tried differnet service station. took filler neck off to see if hose was bad. it was a lil bent but still plenty of room for gas to go in. but coming out of the gas tank was a smaller hose that was inside filler neck. yes, i mean down in gas tank into hose, not the vent tube on side of filler. what is that? is it suppose to be there? someone siphon gas a break it?
