Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shocks.
Relieve fuel system pressure by removing the fuel pump relay and running the engine until it stalls.

2. Access the Fuel Pump

Raise the vehicle using a jack and secure it on jack stands.
Remove any necessary components (e.g., fuel tank shield) to access the fuel tank.
Disconnect the fuel lines and electrical connectors from the fuel pump module.

3. Remove the Fuel Pump

Unscrew the fuel pump module retaining ring using a specialized tool or a flathead screwdriver.
Carefully lift the fuel pump module out of the tank, ensuring not to damage the float arm.

4. Inspect and Replace

Inspect the old fuel pump for signs of wear or damage.
Install the new fuel pump and ensure the O-ring is properly seated to prevent leaks.
Reinstall the retaining ring and tighten it according to manufacturer specifications (typically hand-tight).

5. Reassemble and Test

Reconnect the fuel lines and electrical connectors.
Reinstall any components removed to access the fuel pump.
Reconnect the battery and start the engine to check for proper fuel delivery.
