Solution

1. Preparation

Gather tools and parts:
- Tools: Socket set, fuel line disconnect tool, torque wrench, flathead screwdriver, safety goggles, gloves
- Parts: New fuel filter, O-rings (if necessary)
Relieve fuel system pressure:
- Locate the fuel pump relay in the fuse box.
- Start the engine and remove the relay to stop the fuel pump.
- Allow the engine to run until it stalls to relieve pressure.

2. Access the Fuel Filter

Disconnect the negative terminal of the battery to prevent electrical shorts.
Raise the vehicle using a jack and secure it with jack stands.
Locate the fuel filter, typically found along the fuel lines near the rear of the vehicle.

3. Remove the Old Fuel Filter

Use the fuel line disconnect tool to detach the fuel lines from the filter. Be prepared for some fuel spillage.
Remove any mounting brackets or bolts holding the fuel filter in place using the socket set.
Carefully remove the filter from its housing.

4. Install the New Fuel Filter

Compare the new filter with the old one to ensure compatibility.
If required, lubricate the new O-rings with clean engine oil.
Install the new fuel filter in the same orientation as the old one, securing it with mounting brackets or bolts.
Reconnect the fuel lines, ensuring they are properly seated.

5. Reassemble and Test

Reconnect the negative battery terminal.
Reinstall the fuel pump relay in the fuse box.
Turn the ignition key to the "ON" position (without starting the engine) to prime the fuel system and check for leaks around the filter.
Start the engine and let it idle, checking for any leaks or irregular performance.
