I had the strangest thing happen,driving up the road and the truck just died. Primed the filter it would run until the pump emptied and die again. Then fuel running off the back of the engine from somewhere in the valley. Towed it home and began the teardown. Once I could actually see the CP3 I found 4 of the 6 screws that hold the pump together had fallen out! Pulled the pump,loctited and replaced the screws,reinstall everything and the truck runs perfect.
