I had the same problem with my '98. The fittings are stainless steel but they are open to the elements and the spring seizes up with all that crap that gets up in there. The first thing to do is get some WD-40 or PB blaster and soak both fittings. Wait a little bit and soak them again and then use some compressed air and blow it out. Install the compression tool and slowly rock it back and forth to get it to seat all the way down. It should come out.
If it still won't budge you can do two things. Take it to a mechanic and have them try but they will mostly likely do the following thing if they can't get it to budge is either cut the filter and remove the spring and replace the spring which Ford does carry, or they will cut the entire fitting off and use a serivce replacement fitting or you can do it yourself.

Any suggestions for that problem, other than take it a pro, which is what I'm afraid I'll have to do?
