Stumbled upon this article about fuel pumps and thought it might benefit this discussion.

The long and short of it is the cp4 pump is just like the newer pumps in the cm2250/2350/x15 and in pickups fails around the 100,000 mi mark. The cp3 is a different design, not prone to these failures, and was used on cummins pickup engines up until 2018 or 2019.
