I'm ripping the carbon canister out of my chevelle, and have it all figured out (not much to it) with the exception of the line that runs to the fuel tank. Should I cap it off, put a check valve on it or what?
I don't know if you can cap it off since its a non-vented fuel system,mine is still open return line is under the steering column and works fine,seems a one way check valve might be the ticket.I don't know if you can plug it off and get a vented gas cap either.

I would think the hose probably needs to remain open to equalize the pressure in the tank
But I guess if you plug it and the car runs ok with no pressure build up in the tank when you stop after driving several miles it must be ok to plug it
Hopefully someone else will know for sure
Well Bob's reply wasn't there when I replied
but now that he reminded me, We removed the canister from my grandson's 79 Nova and just left the hoses open ended under the hood and there doesn't seem to be any problem with it
