I want to change the Fuel Filter on my 2004 Ford Focus, 2.3l, How do I relieve the fuel system pressure and what is the best way to go about doing this job. I have the filter from NAPA and the tools/device to release the clips on the filter.

The fuel pump relay is located in the engine compartment, in the battery junction box, relay C1051.Remove the fuel pump relay. depressurize fuel system steps



Start the engine and allow to idle until the engine stalls.

After the engine stalls, crank the engine for approximately 5 seconds to make sure the fuel injection supply manifold pressure has been released.

Turn the ignition switch to the OFF position.

When the fuel system service is complete, install the fuel pump relay.

NOTE: It may take more than one key cycle to pressurize the fuel system.

Cycle the ignition key and wait 3 seconds to pressurize the fuel system. Check for leaks before starting the engine.

Start the engine and check the fuel system for leaks.

the fuel filter is located under the car at the right rear in front of tire close to the gas tank, you will need to raise and support the car and release the clips on the fuel filter and remove the screw from the bracket and remove the filter thanks
