How do you change the fuel filter on my 2004 mercury monterey?

To change the fuel filter on a 2004 Mercury Monterey, first, ensure the vehicle is parked on a level surface and the engine is cool. Relieve the fuel system pressure by removing the fuel pump relay and starting the engine until it stalls. Next, locate the fuel filter, which is typically found along the fuel line under the vehicle, and use a wrench to disconnect the fuel lines from both ends of the filter. Replace the old filter with a new one, ensuring the flow direction is correct, and reattach the fuel lines before reinstalling the fuel pump relay.
