[tjs72lemans]

I have a mostly stock rebuilt 400 in my 72 Lemans. Everything on car is new or rebuilt. I am not using the intake valve assembly to control the vapors from the gas tank to the charcoal canister to carb. I was going to plumb it from canister to the port on carb. I know that would mean it is sucking vapors all the time while running. Not sure that is a good plan due to richer mixtures at times. I then thought about just leaving it open to the air from canister with a line running down below to frame. Either with the canister or eliminate the canister all together. Thoughts? Experience?
