Pull the fuse to the fuel pump, start the car, and let it run until it dies. That should bleed off enough line pressure to change the filter safely. I would still wrap a rag or shop towel around the filter when removing to catch any residual gas.
Look for your fuel injector ';rail'; which runs parallel to your spark plugs (this is located above them). Make certain your engine is cold and that you have a rag to absorb excess fuel. Wear safety glasses. On the end of the rail is where you will find the bleeder.
