Fuel Pump Module: Installation

  1. Ensure sealing area on fuel tank is clean. Using NEW rubber gasket, install fuel pump module on fuel tank. DO NOT reuse rubber gasket. Ensure rubber gasket remains in place.
    NOTE: Fuel pump module must be properly positioned in fuel tank to prevent float from contacting the fuel tank.
  2. Rotate fuel pump module so alignment arrow on fuel pump module is at 7 o'clock position and aligns with reference mark on fuel tank. See Fig 2. Install and hand tighten fuel pump module lock nut.
  3. Note location of fuel pressure regulator on fuel pump module. See Figure. Ensure fuel filter/pressure regulator is positioned on fuel pump module so fuel line fitting on side fuel filter/fuel pressure regulator points toward driver's side of vehicle.
  4. Hold fuel pump module in place while tightening fuel pump module lock nut to specification. See TORQUE SPECIFICATIONS . Reinstall fuel tank using proper procedure.
