Unplug it all, and plug any holes!

Only thing I never understood, was what to do with the vapor line coming from the fuel tank?

I might try to simply cut it off and plug it as close to the tank as possible...lol I've been plugging and capping alot of holes lately on that car...lol Thanks for the info.

You cant plug the line to the tank. Tank has to be vented or you'll suck a vacuum and stall the car. I left mine open but kept smelling fumes.. so i connected it to my bowl vent on my carb.. For you efi guys thats basically just venting it into the air filter housing.

OK, I'll go with plan B and vent it into the carb somehow...lol.

So, vent it to the intake tube somewhere?

If the cansiter vapor line is for "venting," what's the 4th line from the tank for, that has some sort of check valve that's right next to the tank itself?

No idea. Maybe it is a vent and the canister only vents high pressure vapor. Which means you still have to vent it somewhere or on hot days your tank will swell up like a balloon.

Yes, just vent into the intake tract somewhere. Not where theres much vacuum though just filtered to atmosphere basically.

That should be easy when I get the cold air and filter over to that side.

How could you hook it to a aftermarket intake tubing and not get a lot of vacuum...? I'd like to ditch the canister as well...

Maybe just remove the check valve then, and make it a both way tank?

Do we NEED pressured tanks? Vacuum really doesn't happen until it hits the throttle body and plenum, after the throttle blades. It's all ambient air before the blades, afterward is where the engine is sucking. Think of the blades as a straw, that you're sucking through.

Sure there is some pull on the air before in an intact tract.... don't know that it's enough.

I get hissing with that vent tube still hooked up.
