I bought a 1982 750 LTD A couple of years ago, my son took the gas tank off to paint when I was overseas in the Air force. Anyway, I ended up painting it & ready to put it back on. There is a small line comming out of a carb (which I think is a vacuum line that goes to the petcock) & one larger one out of the tank (which I think is the fuel line) that I have no idea where that goes to the carbs. wondering if someone could help me out to explain where the go. Thanks Dave
