A fuel filter isnt going to make a check engine light come on , unless its complete stopped in which it will kick misfire, manfacture codes, etc...I have fixed 1,230,00 fords with this same code all but a few was the MAF never ever being a fuel filter..... Not to mention if you read his post he has already replaced the filter so everything your saying isnt making any since good day mate!

I can't count the number of times I've found a clogged fuel filter on a ford, and has corrected a lean condition. And lots of those times, the clogged filter burned up the pump.
