Removal Procedure

  1. Remove the fuel tank filler cap.

  2. Object Number: 63084  Size: SH
  3. Open the air bleed valve on top of the fuel manager/filter in order to release any of the pressure in the fuel supply system.
  4. Remove water in fuel senor connector at bottom of filter.

  5. Object Number: 64313  Size: SH
  6. Drain the filter by attaching a flexible tube or hose (1/4 to 5/16 in. I.D.) to the water drain valve.

  7. Object Number: 64302  Size: SH
  8. Slowly open the water drain valve (the drain does not have to be totally removed for fuel to drain).
  9. Turning the locking ring in a counterclockwise direction. If unable to turn by hand, use a strap wrench (oil filter type) in order to break the element nut loose.
  10. Remove the element by pulling straight down.
  11. Remove the Water In Fuel/Sensor from element.

Installation Procedure

Important: The new element is not equipped with a water in fuel sensor, only a plug. The water in fuel sensor/valve must be removed form the old element. Use the new seal (attached to the plug) to replace the old seal on the water in fuel sensor/valve.

Make sure that the mating surface between the element assembly and the filter assembly is clean before installation.


    Object Number: 64302  Size: SH
  1. Install water in fuel sensor/valve with new seal.
  2. Install the new element by aligning the arrow on the element to the air bleed drain valve on header assembly.
  3. Push the element in a upward direction until the mating surfaces make contact.
  4. Align the locking ring on the filter header assembly.
  5. Tighten
    Tighten the locking ring securely by hand. A "click" noise will be herd (arrow on the locking ring will be aligned with the arrow on the element).

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  6. Install the connector on the water in fuel sensor/valve.
  7. Reinstall the fuel tank filler cap.
  8. Bleed the air from the fuel manager/filter. Refer to Fuel Supply System Air Bleed .
