    Default Fuel line diagram

    I'm double checking my work, trying not to make any mistakes that will cost me in the long run

    Does anyone have a fuel line/system diagram??

    Thanks all! 😁

    Two lines run from the tank to the engine bay.

    Larger one is the feed from the tank to the fuel lift pump and then on to the engine fuel filter.

    Smaller line is the return line back to the tank.

    The return line is fed by a "manifold" (Well sort of) that picks up all the injectors and the return from the IP.

    The incoming line feeds the filter and then from the filter on to the IP inlet.

    The water drain /purge line goes from the bottom of the filter under the intake manifold to the water drain cock at the front of the engine and then drains to the ground when the cock is opened up.

    Hope this helps
