Solution

1. Preparation

Gather tools needed: socket set, fuel pressure gauge, safety glasses, and rags.
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.

2. Remove Fuel Filter

Locate the fuel filter; it is usually found along the fuel line in the engine compartment or under the car.
Use a socket set to remove any bolts securing the filter bracket (if applicable).
Carefully disconnect the fuel lines from the filter; be prepared for fuel spillage, using rags to catch any spills.

3. Inspect and Replace

Inspect the old fuel filter for any signs of clogging or damage.
Install the new fuel filter, ensuring the fuel flow direction is correct (indicated by arrows on the filter).
Reconnect the fuel lines securely.

4. Reassemble and Test

Reinstall any brackets or covers removed during the process.
Reconnect the fuel pump relay.
Turn the ignition to the "ON" position without starting the engine to prime the fuel system.
Check for leaks around the fuel filter and lines.
