Remove the rear seat cushion (if applicable) to access the fuel pump module.
Detach the access panel covering the fuel pump.

3. Remove the Fuel Pump

Disconnect the electrical connector from the fuel pump.
Relieve the fuel system pressure by removing the fuel filler cap and using a rag to catch any residual fuel.
Unscrew and remove the retaining ring or bolts securing the fuel pump module to the fuel tank.
Carefully lift the fuel pump assembly out of the tank, ensuring not to damage the fuel lines.

4. Inspect and Replace

- Install the new pump into the fuel tank, ensuring it seats properly.
- Secure it with the retaining ring or bolts to the specified torque (check manufacturer specifications).

5. Reassemble

Reconnect the electrical connector to the fuel pump.
Replace the access panel and rear seat cushion.
Lower the vehicle from the jack stands.

6. Final Checks

Reconnect the negative battery terminal.
Turn the ignition to the "ON" position (without starting) to prime the fuel system.
Check for leaks around the fuel pump area.
