Based on this comment. Two Detroit Diesel engineers have inspected the HFPP from my truck. No water, no sign of particle contaminants...just an under lubricated and overheated pump assembly.
Makes me wonder what pressures and line sizes are used in the GM and Ford trucks from the tank to the High Pressure pump. Sounds alot like the old issue of the lift pump not supplying enough pressure and fuel to the High Pressure Pump, just like the older Dodges did when the had that Carter Lift Pump that would fail or drop pressure then take out the High Pressure Pump.
