Thread: Fuel Pump Position

  1. #1

    Default Fuel Pump Position

    I hope this is the last question I have for you. I appreciate your assistance so far.

    I'm having difficulty placing the fuel pump in a position which is lower than the fuel tank.
    It would mean that the pump would sit well proud of the chassis rail, placing it in a dangerous position.

    I'm looking at the idea of adding a surge tank, but this means I will have another fuel pump that can fail and leave me stranded.

    How imperative is it that the pump sits below the tank line?
    What would be the best way around this issue given that finding an ideal spot for the pump is not an option?

    It's not imperative.
    My external in-line fuel pump has never been mounted below the level of the fuel tank.
    It's more important to mount the fuel pump as close to the tank as possible, keeping the suction line as short as possible.
    Drill the pump's inlet fitting a little larger, and use the shortest possible suction hose.
    My fuel pump has been mounted at the top of the fuel tank for over 14 years and never had any problems.
