Solution

1. Preparation

Gather necessary tools and parts.
Tools Required:
- Socket set
- Wrench set
- Fuel pressure gauge
- Safety glasses
- Shop towels
Parts Required:
- New fuel filter
- Fuel line disconnect tool (if necessary)
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Relieve Fuel System Pressure

Locate the fuel pump relay in the fuse box (refer to owner’s manual).
Remove the fuel pump relay.
Start the engine and let it run until it stalls, indicating that the fuel pressure has been relieved.
Turn off the ignition and disconnect the negative battery terminal.

3. Remove Old Fuel Filter

Locate the fuel filter, typically found along the fuel line under the vehicle.
If necessary, use the fuel line disconnect tool to free the fuel lines from the filter. Be prepared for some fuel spillage; use shop towels to catch any fuel.
Unbolt the fuel filter from its mounting bracket using the appropriate socket or wrench.

4. Install New Fuel Filter

Position the new fuel filter in the mounting bracket.
Secure the filter with bolts, ensuring it is firmly attached.
Reconnect the fuel lines to the new filter, ensuring they are properly seated and secured.

5. Reassemble and Test

Reconnect the negative battery terminal.
Reinstall the fuel pump relay.
Turn the ignition to the "ON" position (do not start) to prime the fuel system, and check for leaks around the filter.
Start the engine and allow it to idle, monitoring for any signs of leaks or irregular operation.
