Place a rag around the fuel lines to catch any fuel spillage.
Use a fuel line disconnect tool to detach the fuel lines from the pump.
Disconnect the electrical connectors from the fuel pump by pressing the release tab.

4. Remove the Fuel Pump Assembly

Unscrew the retaining ring that holds the fuel pump assembly in place using a special tool or a hammer and flathead screwdriver.
Carefully lift the fuel pump assembly out of the tank, ensuring the float arm does not get damaged.

5. Inspect and Replace Fuel Pump

Check the old fuel pump for signs of wear or failure.
If replacement is necessary, install the new fuel pump into the assembly.
Ensure the fuel filter attached to the pump is clean and not clogged.

6. Reassemble and Test

Reinstall the fuel pump assembly into the tank and secure it with the retaining ring.
Reconnect the fuel lines and electrical connectors.
Replace the access panel and secure it with screws or bolts.
Reconnect the battery and perform a fuel pressure test to confirm proper operation.
