I have a 57 chevy truck, i installed a new fuel tank today. I put everything back perfectly except the vent hose. The vent hose that it had was cracked. Went to auto zone replaced the vent hose. I noticed that the old piece of hose had paper shoved into it. I put the new vent hose on, started the truck, went to the store to fill up. Came home, went inside. 1 hour later, leaving for church, there is fuel spewing from the cap! Fuel was coming out of the key hole, my paint was blistered. I immediatly took the cap off n u can hear the tank gargling!! I went to church, when i got back the fuel was still gargling even with the cap off! Do i need to plug off the vent tube like it was? Isnt that what the vent tube is for? Mind u, i have replaced the tank before in this truck but the bracket behind the tank that connects the body to the floor made two little holes in the tank, so i bought a new one. Got any answers out there, thanks. Leo

Suggest locking fuel cap - right? Bet is that isn't original designed for 1957. Something with proper venting and cap just isn't right and hard pressed to guess at this too much. Could be difficult to find correct cap but would be out there somewhere. Vent hose was possibly designed to prevent fast flow of any liquid fuel from top of tank to higher up on neck of filler area and not doing its job.
Tons of vehicles even later would shoot fuel out just while filling too fast while even just filling too fast. Hard to say what original intention was but wouldn't IMO be real paper in vent hose but should have been something more fuel tolerant,
