Inspect the Old Pump:
- Examine the old fuel pump for signs of wear or damage.
Install New Fuel Pump:
- Place the new fuel pump into the assembly, ensuring it is oriented correctly.
- Reinstall the retaining ring or screws securely (consult the service manual for torque specifications).

4. Reassemble and Test

Reconnect Fuel Lines:
- Attach the fuel lines to the new pump, ensuring they click into place.
Reconnect Electrical Connections:
- Plug the electrical connector back into the fuel pump.
Reinstall Access Cover:
