I had trouble removing the cap for the fuel filter. Of course the 1/2" drive just chews up the hole. So I'm posting a picture of the method I used. I actually used a long pry bar for leverage instead of the screwdriver seen in the picture. It made it very easy to remove using this method. I tried the Motorcraft filter, but I removed the old one and realized that the cap had the pre-filter/screen molded to it. So I had to change the cap and filter this time.

if you have the 6-prong socket for old style 4WD wheel bearing jam nuts, that works slicker-n-snot
