Be sure you release the pressure in the fuel line first by pressing the schrader valve or pulling the fuel pump fuse and cranking the engine.
Keep a big rag against the filter when disconnecting the nut and clip.
Changing your fuel filter is important because a dirty or clogged filter will make your fuel pump work harder than it normally would to keep proper pressure causing your fuel pump to run hot and shorten the life of your fuel pump.
If you can't change your own fuel filter in your car I'm afraid you'll have to turn in your man card.
