Removal Procedure

    Important: DO NOT handle the level sender on the resistor card. Oils from human contact can damage the card.

  1. Remove the module from the fuel tank. Refer to Fuel Tank Fuel Pump Module Replacement - Right Side .

    2. Object Number: 1690257 Size: SH
  2. Press on the 3 connector position assurance (CPA) lock tabs (1) and slide downward.
  3. Disconnect the electrical connector from the module.
  4. Remove the sender wires from the electrical connector.

    5. Object Number: 1690260 Size: SH
  5. Push in the lock tab (1) above the level sender body and slide the level sender out of the slot.
  6. Remove the level sender from the module. Ensure wires are routed into the slot in the back of the level sender body.

Installation Procedure

    Object Number: 1690260 Size: SH
  1. Insert NEW level sender assembly into slot and slide down until lock tab (1) engages.
  2. Route wires next to regulator ground wire and up to electrical connector.
  3. Slide the level sender wires into the open slots in the electrical connector.
  4. Connect the electrical connector into the flange.
  5. Test the level sender resistance with an ohmmeter.
    6. 5.1. Empty stop = 38.5-41.5 ohms.
    5.2. Full stop = 247-253 ohms.
    5.3. No open circuits along the full sweep.
  6. Install module into tank. Refer to Fuel Tank Fuel Pump Module Replacement - Right Side .
  7. Measure the resistance across the level sender with tank upright. Should read empty tank.
  8. Roll tank over. Resistance should read full stop.
  9. Return tank to upright position. Ensure proper empty stop resistance. This is done to ensure the level sender operates freely inside the tank and is not hung up on any of the internal lines.
