[QUOTE="Black AOD, post: 1541899, member: 16536"] The big majority of CP4's failing are due to poor diesel fuel put into the truck or lack of fuel filter changes and maintenance. New 2020 CP4's went from 29K PSI max RP to 36k PSI max RP and they changed the internal cam and a few other small things to help with the higher pressures.... new 2019 and 2020 Dodge Cummins have the same CP4 as the 2020 Ford as well.
