TrevorG is right. The small line in the upper right, by trottle cables goes to petcock. Since you changed petcock, close that one off. The upper left is overflow. Then there is the bowl drain hose. I then have hose at front of carb. that goes down to a canister on frame. The only other hose is the gas line from petcock to carb. Hope this helps.
