Ensure the vehicle is parked on a level surface and the engine is off. Allow the vehicle to cool down before starting work.

2. Relieve Fuel System Pressure

Locate the fuel pump fuse in the fuse box.
Start the engine and remove the fuse to cut power to the fuel pump.
Allow the engine to stall, indicating that fuel pressure is relieved.

3. Access the Fuel Filter

Depending on the configuration, the fuel filter may be located under the vehicle near the fuel tank or in the engine bay.
If necessary, raise the vehicle using jack stands for access.

4. Remove the Old Fuel Filter

Using the fuel line removal tool, disconnect the fuel lines from the filter. Be cautious of residual fuel that may spill.
Remove any mounting brackets or screws holding the filter in place using the socket set.
Carefully take out the old fuel filter.

5. Install the New Fuel Filter

Compare the new fuel filter with the old one to ensure correct fitment.
Install the new fuel filter in the same orientation as the old one.
Secure the filter with any mounting brackets or screws previously removed.
Reconnect the fuel lines, ensuring they are properly seated and secured.

6. Restore Fuel System Pressure

Reinstall the fuel pump fuse in the fuse box.
Turn the ignition key to the "ON" position without starting the engine for a few seconds to prime the fuel system.
Check for leaks around the fuel filter and connections.

7. Final Steps

Start the engine and allow it to run for a few minutes to ensure proper operation.
Monitor for any unusual noises or check engine light activation.
