Tools Required: Socket set, screwdrivers, fuel line disconnect tool.
Remove the rear seat or access panel to reach the fuel pump assembly.
Disconnect the electrical connector from the fuel pump.
Use the fuel line disconnect tool to carefully detach the fuel lines from the pump.
Unscrew the retaining ring or bolts securing the fuel pump to the fuel tank and remove the pump assembly.

3. Inspect and Replace

Inspect the old fuel pump for signs of wear, damage, or blockage.
If the pump is faulty, install the new fuel pump in reverse order of removal.
Ensure that all seals and gaskets are replaced to prevent leaks.
Reconnect the fuel lines and electrical connector securely.

4. Reassemble and Reconnect
