Solution

1. Preparation

Gather tools and parts: OBD-II scanner, fuel pressure gauge, socket set, new fuel filter, safety goggles, gloves.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Relieve Fuel System Pressure

Locate the fuel pump fuse in the fuse box and remove it.
Start the engine and allow it to run until it stalls, indicating that fuel pressure has been relieved.
Turn off the ignition and disconnect the negative battery terminal again for safety.

3. Remove Old Fuel Filter

Identify the location of the fuel filter (usually along the fuel line under the car or in the engine compartment).
Using the appropriate socket or wrench, carefully remove the mounting brackets or clamps securing the fuel filter.
Disconnect the fuel lines from both ends of the filter, taking care to catch any residual fuel in a container.
Remove the old fuel filter and inspect the O-rings for damage.

4. Install New Fuel Filter

Take the new fuel filter and ensure that the flow direction matches the markings on the filter.
Attach the fuel lines to the appropriate ends of the new filter, securing them tightly to prevent leaks.
Reinstall the mounting brackets or clamps to secure the filter in place.

5. Restore Fuel System Pressure

Reinstall the fuel pump fuse in the fuse box.
Reconnect the negative battery terminal.
Turn the ignition key to the "On" position (without starting the engine) to allow the fuel pump to pressurize the system.
Check for any leaks around the fuel filter connections.
