    Fuel lines

    I am about to hook up my FMU. I know its not the best, but for now it should make the car run. So Is the bigger line or the smaller line the feed line. I am trying to figure out what is what.

      For my Beretta the 3/8" is the feed and the 5/16" is the return. I think that goes for most 60*v6 fuel injected cars.

        remeber to hook the FMU to the return line. And make sure you also hook the FMU up properly. If i remember the FMU should be "In from the fuel rail to the Side" and "Out to the hard line from the Center". like SO:


        On the fuel rail the Larger line is the feed (rear line if your standing at the front of the car) and the smaller is the return (the line closest to the front of the car). I replaced my stock fuel line with a new rubber fuel line to run to the fmu and then also from the fmu to the hard return line. my feed line is the stock line.

        hope this helps.

            Bigger is always feed, smaller is always return.
            I may own a GTO now, but I'm still a 60V6er at heart.
