How often should I change my fuel fliter and do the 6.4 have two fliters or just one, If they have two should you change them both at the same time?
They are both changed at the same time. Suggested interval is 20,000 miles, normal service and 10,000 miles, severe service.
Both filters come as a package deal from Motorcraft. I don't know of any source where you can buy them separately. I stick with OEM filters although some would disagree.

Reason: typos
10,000 miles......packaged from FORD (2).........36mm filter wrench from SEARS makes it easy..... The top filter is easy. The bottom filter is a bear. Good luck.
