Other then the line that goes from the canister to the fuel tank, where do the other lines go? Vent to atmosphere? One reads AC and another reads to carb (I have FI and no AC). Another question, What are some possible problems I could encounter if I was missing a separator tank (the one that attaches to the underside of the body not the fuel tank on the passenger side? Any help would be appreciated!
