Thread: Fuel lines

  1. #1

    Default Fuel lines

    So I messed up, when I pulled my motor for the 2nd time i forgot to disconnect the fuel lines and they both snapped. They snapped so easily it was probably for the best. So I went and bought some FI fuel line, but I cannot figure out which line goes in which. The quick connects are two different sizes and I know one is a return line, so I was hoping someone here can tell me if the front or rear fuel hardline (or left or right looking at them from the pass side down into the engine bay) is the correct for the main and which is the return.

    The metal connectors should be slightly different sizes. If you remove the fittings, the pipe end is fairly obviously bigger.
