re: fuel filter replacement... I've tried this myself and failed miserably. I couldn't get the dang connector off. You might have better luck.
A tip: remove the fuel pump fuse, then start the engine and let it run til it dies. This removes pressure from the fuel system so that you don't get sprayed with high pressure gas when you remove the filter.
