How do you change a fuel filter on a 2004 mercury monterey?

To change the fuel filter on a 2004 Mercury Monterey, first, relieve the fuel system pressure by removing the fuel pump fuse and running the engine until it stalls. Once the pressure is released, locate the fuel filter, which is typically found along the fuel line under the vehicle. Disconnect the fuel lines from the filter using a wrench or pliers, then remove the old filter and replace it with a new one, ensuring the flow direction is correct. Reconnect the fuel lines, replace the fuse, and start the engine to check for leaks.
