Fuel Tank Vent

I have a '62 chevy pickup w/ the tank mounted in the cab. Ever since I have had it it has been hard to fill the tank. I usually need to put fuel in very slooooow. Recently I let the fuel level get near empty and I got a big woosh of air when I opened the tank. It is apparent that the cap is not vented. Is there any other vent for this tank? It is not venting into the cab. Any other ideas?

There is a conversion that takes the tank out of the cab & puts it under the bed .

I even saw one that was for a step side & the filler was under one of the boards It was hinged to gain access.

I don't think those are vented for the obvious reason .

Have you tried different angles of holding the nozzle?

Rob,
Thanks for the reply. I really don't want to relocate the tank, although that kit would probably solve the problem. Holding the nozzle at various angles only increases oe decreases the amountt of overflow when full. The previous owner reported no problems. It's a minor aggravation but I would like to resolve the situation.

On a 62 your gas cap should be vented.

On fuel injected cars the cas tank is not vented to help build a head pressure for the pump so it doesn't cavitate.

With your gas tank inside the cab like that you don't want any pressure in the tank for a couple reasons, one, you have a carberator, if there is pressure in the tank it will always be pushing gas into your float bowl. Two, if the fumes aren't leaving the tank via the gas cap, they are escaping into the cab with you (hope you don't smoke).

You might want to find out if you have the right gas cap for your truck.

As far as putting fuel in it, I've got a 64 GMC that is the same way, if I get gas somewhere that doesn't have the little rubber guards on the pump nozzle I just lock the handle and stand back cuz it's gonna shoot a little fountain when the tank gats full before the automatic shutoff thingy gets it shut off. (only took one soaking to learn that one)

Good luck...

man !. . . . What a poser!! i mean its not like there is a length of hose with a few twist turns & kinks in the fill neck .

Have you looked down into the tank to see if maybe your neighbors kid threw some ping pong balls in there?.

I agree the cap should be vented .

Is it a hard fill all the time everytime?
or just in certain spots of the fill up?

I remember those old Chevy's like the 75 to 85 with the dual tanks you had to turn the nozzle upside down to fill them up & certain ones had a personal trick or two about them.

{1st hand gas station attendant experience }

LOL

Well let us know if you finger it out OK?
