gas tank vent size?

Primal_Scream · Nov 11, 2016

Can anyone tell me what size rubber fuel line do I need to buy for the vent line that goes into the trunk? the person before me put a new tank in and had capped the line off.

I think it is a 1/2" hose

Used 1/4" on my Bee to connect to my tank fittings.

Don't use rubber, use neoprene. No pressure on them but rubber will swell.

You're talking about a later b-body right? Not a 66-67! I believe that is correct! 1/4" both to the tank.

Primal if it's a stock tank the pickup line is either 5/16 or 3/8. Vents use 1/4".
