OK, I just got my new tank in, now the new one isn't like my 72 original, the old one had vents on the corners and it all went back to a canister. the new one is like everyone after 72, my question is this, I have 2 vent tubes on the left side of the tank opposite the fill tube, I would assume one is for the return line from the front, is the other the vent?? if so can I just run this to a hose that will be away from any water like the vent tube for the driveshafts? oh and what should I paint it with, will rustoleum do? or do I have to paint it with something special for the tank steel?
