Wondered if anyone has ever changed the fuel filters on the DD15 themselves. I've changed the fuel filter on the frame under the cover. Had an issue with a T/A improperly replacing the water separator filter when I first got the truck. Since then, I only change them at the dealership. Speedco gave me the filters when I had the service done last. So I was thinking of giving it a go. Can't get mad at myself if I mess it up.![]()

Not as easy as a spin on but still quick. Just take care not to get a kink in the o-rings.
Edit: You'll need a 36mm socket and torque wrench.Shadetree Trkr Thanks this. -
If it's a davco, super simple, but there is a proper procedure and special tool needed.

DO NOT CHANGE THEM AND THE OIL FILTER AT THE SAME TIME also. There was a service bulletin about this after dealerships blew up a few Detroit and Mercedes due to having to crank them over so long to pick up fuel with no oil pressure.
My DD15 has to run quite a while at road RPM before it will start normally again after the fuel filter.
So do them one at a time running the truck in between. -
