Sacmandmax--I noticed in your post that you said you put in a "new" magnet when you installed the new spin-on tranny filter on your Allison. Maybe just a slip on your part, calling it "new", but the magnet is reusable. All you have to do is clean it off and put it back in.
When I replaced my fuel filter at 15k miles, I did it without taking the skirt off the fender well. Only problem I had was that the rubber grommet that fits around the fuel inlet(?)--the part the filter screws onto--stayed on the filter housing. Had a hell of a time figuring out why the new filter wouldn't screw on, then even more fun trying to get the old grommet off. That's when I resorted to a 6-pack of "penetrating fluid"!
