    Note

    When handling the supply pump, be sure to hold it by the housing. Do not hold it by the fuel pipe, fuel temperature sensor or suction control valve.

    Tech Tips

    If the engine room is very dirty, clean the fuel pipe and the area around the fuel temperature sensor connector before removing the supply pump from the vehicle.

  2. CLEAN SUCTION CONTROL VALVE AND SURROUNDING AREA


    1. Place the supply pump in a tray of clean diesel fuel and clean the area around the suction control valve as well as any areas that contact other parts using a brush. After that, clean the part using cleaning spray, cloth, etc.

      Note


      • After cleaning with cleaning spray, do not blow air as doing so will cause any dust or sand in the surrounding area to become airborne and adhere to the cleaned area.

      • Do not allow the fuel temperature sensor connector or fuel pipe to face downward while performing this step.

      • Check that there is no dirt or foreign matter between the suction control valve and fuel supply pump housing.
