I have searched on here and if I have missed it please forgive me I am looking for a complete FSM or fuel system diagram for the 4.2l wrangler YJ. I have a diagram of the fuel tank and carburetor but I need the diagram showing the fuel lines to the mechanical fuel pump on the passenger side of the jeep to the fuel tank I have a fuel line going no where and I am not sure where it should be going. Unless maybe it is a fuel return line? I have the line going to the fuel tank to the pump and the n pump to the carburetor so after that I am lost. Sorry I am brand new to this so I am learning as I go. Chilton manual no help google no help either. Or at least I am not searching correctly.
