Park the vehicle in a well-ventilated area and ensure the engine is cool.
Disconnect the negative battery terminal to prevent electrical issues.

2. Relieve Fuel System Pressure

Locate the fuel pump fuse in the fuse box and remove it.
Start the engine and let it run until it stalls to relieve pressure in the fuel lines.
Turn the ignition off and disconnect the fuel pump relay.

3. Access the Fuel Filter

Locate the fuel filter, which is usually found along the fuel line underneath the vehicle.
Use the socket set to remove any mounting brackets or clamps securing the fuel filter.

4. Remove the Old Fuel Filter

Use the fuel line disconnect tool to carefully disconnect the fuel lines from the filter, ensuring not to damage the lines.
Position a drain pan under the filter to catch any residual fuel.
Remove the old fuel filter from its mounting location.

5. Install the New Fuel Filter

Ensure the new fuel filter is oriented correctly (check for flow direction arrows).
Connect the fuel lines to the new filter using the fuel line disconnect tool, ensuring a secure fit.
Reinstall any mounting brackets or clamps to secure the new filter.

6. Restore Fuel System Pressure

Reinstall the fuel pump relay and fuse.
Turn the ignition key to the "On" position without starting the engine to allow the fuel system to pressurize. Check for leaks around the new filter.
Start the engine and let it run for a few minutes to ensure proper operation.
