2. Access the Fuel Filter

Locate the fuel filter, typically found along the fuel line under the vehicle or in the engine compartment.
If located underneath, raise the vehicle using a jack and secure it with jack stands.
If necessary, remove any protective covers or shields to access the fuel filter.

3. Remove the Old Fuel Filter

Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Use the fuel line disconnect tool to detach the fuel lines from the filter carefully. Be cautious as fuel may spill.
Remove the mounting bolts or clips securing the fuel filter to the vehicle.
Carefully take the old fuel filter out.

4. Install the New Fuel Filter

Compare the old fuel filter with the new one to ensure compatibility.
Install the new fuel filter in the same orientation as the old one, ensuring the flow direction is correct (usually indicated with arrows on the filter).
Secure the filter with the mounting bolts or clips, tightening to the manufacturer's specifications.
Reattach the fuel lines, ensuring they are firmly connected and properly seated.

5. Final Checks

Reinstall any protective covers or shields removed during the process.
Reconnect the fuel pump fuse and the negative battery terminal.
Start the engine and let it run for a few minutes while checking for leaks around the fuel filter.
