gas tank vent size?

[Primal_Scream]

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.

i am replacing the tank in my roadrunner,do i use 1/4 for both trunk vent lines?do i connect both lines to the two vents on gas tank?

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".
