Driving down the freeway got the message for low fuel pressure. Few seconds later in to limp mode. Barely got off the freeway safely. AAA towed my truck to the Dealer. My HPFP grenaded at 9300 mil...

I'm still running all OEM fuel and emissions systems on my RAM 6.7L. So far no major issues and hope none come. I think I'm glad I have the Bosch CP3 in my truck. Not that I can't have problems, but it sure seems like these CP4 grenades are a nightmare.

Yeah the two piston CP4 pumps out higher max pressures than the three piston CP3 found in the Cummins 6.7L with less volume for lubrication. Not a good combo with ULSD.
