Bosch CP4. POS pump. Ford, Chebby and Dodge (until 2021 model year) used them. Dodge started using a modified CP4, called a CP 3.3, pump sometime after the 2021 model year.
The problem could likely be caused by faulty design and inadequate testing. BOSCH, as most of you know, is a German firm. They make lots of good car parts. However, from what I can gather, Bosch did their testing in Europe where diesel has a higher lubricity that the ULSD in the US.
My dad got his 1931 Ford (I have it and the original title) and ever since then I (now that dad is dead) have bought nothing but Ford trucks. Two 6.9s, 4 7.3s, (no 6.0 or 6.4) and 3 6.7s. Fuel and oil filters changed every 5K. Never a problem with anythting....except...that POS fuel pump. Luckily they both died in my driveway.
Ford tried to sell me a loaded F450 at $10K over MSRP. Not gonna happen.
A local Ram dealer offered to order a 3500, loaded the way I want it, for invoice.
