CP4 has been improved over the many years it has been out.
And is Bosch now paying Eldebrock to use patent for roller cam follows that do not turn sideways in the bore? Lack of good filtration ahead of the CP4.2 was one of Ford's issues with the pump along with warranty denials. At least GM just warrantied them until they could no long stand the failures and switched to the Demso pump.
It will be interesting to see how RAM does with the CP4.2 on the 2019+ models.
