My experience when towing back from Az to Wa st in march of 05 driving a new 05 with 3625 miles and the fuel filter made the truck go into limp mode. after the tow to Blythe Ca and the miss diagnose on what the problem was it was at that time I knew I would get what ever was needed and be able to change the fuel filter if needed on the road and have replaced it each summer in my garage.
My thinking is replace a fuel filter once a year and not the miles driven.
Might have to change my name to OVERKILL chevman
