It has been a while since I took the tank out and I can't find my notes as to what goes where. It seems obvious but I would hate to get it wrong. Can you, or anyone, help me? Thanks

Check posts #29 & #36 and look at where the lines go. If you have 3 lines going from the front to the back, the one to the left goes to the charcoal canister. Not the return of the fuel pump. In the group of 3 lines, the left goes to the fitting on the left side of the tank. The middle to middle, right to right. The new tank should have 3 fitting on it to accept these lines. Then your supply and return lines from the fuel pump go to the sending unit.
