Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.

2. Remove Fuel Pump Access Panel

Locate the fuel pump access panel (usually under the rear seat or in the trunk).
Remove any screws or clips holding the panel in place using a socket set.
Carefully lift the panel to expose the fuel pump assembly.

3. Disconnect Fuel Lines and Electrical Connector

Place a rag around the fuel lines to catch any residual fuel.
Use a fuel line removal tool to disconnect the fuel lines from the pump assembly.
Disconnect the electrical connector from the fuel pump.

4. Remove Fuel Pump Assembly

Unscrew the retaining ring or bolts securing the fuel pump assembly using a socket set.
Carefully lift the fuel pump assembly out of the fuel tank, ensuring the float arm is not damaged.

5. Install New Fuel Pump

Place the new fuel pump into the assembly and reconnect the float arm.
Secure the pump assembly in place with the retaining ring or bolts.
Reconnect the electrical connector and fuel lines, ensuring they are securely fastened.

6. Reassemble and Test

Replace the fuel pump access panel and secure it with screws or clips.
Reconnect the negative battery terminal.
Start the engine and check for leaks around the fuel pump assembly.
