Many Ford dealers have them, it's just you can't find the part # on Motorcrafts website! I bought mine from the dealer, after fighting with the parts counter person, I asked for a mechanic. I don't have the part #, but I know most dealers have them. The parts counter will try to sell you the whole fuel line, so it's best to talk to a service adviser. It's ridiculous of Ford to screw Taurus/Windstar owners like this when it comes to a part needed for a simple maint task like a fuel filter.
