I have been told I should change my fuel filters every third oil change, which I have done since I owned my truck.
IMO, keeping clean oil and fuel running through our expensive injectors is a very, very good idea!
I found that if you loosen the allen head screw on the frame rail filter housing first, the fuel in the lines/filter will drain out of the system. Doing this will prevent spilling a lot of fuel if you remove the filter cap first.
I have been advised by a diesel mechanic friend, to only use Ford or International fuel and oil filters in our trucks, and to avoid cheaper aftermarket filters.
