I just changed the fuel filter on my 2003 Aviator and it was a pain. Aftwer looking and looking I finally found it. It is located under the truck at the center of the front crossmember behind a shield. Two bolts hold the shield and there are two quick release hoses on the fuel filter itsself. Good luck!!!

It means something is wrong with it. Start with fluid level check, idling , warm fluid, in park....
