Default Changing a Fuel Filter

IS there anything special I have to do before I replace my fuel filter. Or do I just unscrew it and then press on the top to prime it?

Be sure to clean the water in fuel sensor.

Unplug the wif sensor first. Sometimes it is easier to remove the inner fender liner. It is on my truck anyway.

Danny has a good write-up here:

unscrew the bleed screw too to make the pumping easier.

Because you replaced the filter, the light should go out after 5 good key trips.
