I think we are at the point where the credibility of the claim of double digit failure rates on a 2 year old 6.7 pumps you experienced need to be verified.
Suggest you PM ricatic, and then arrange a time to chat with him.
The entire forum do not need to know who it is, but to have the data set credibly believed, it need to pass the smell test.
The data is so discrepant with the NHTSA data that I would not put it out until it is at least, minimally verified.
Yes I agree that the issue we are seeing is not reflective of all 6.7L pumps. To me, the most telling thing from all that NHTSA data were the records of 110 warranty replacements at the very end of one of those gigantic documents. The majority of them had the pumps sent back to Bosch and you could see the comments from Bosch after they did tear downs and what they deemed to be root cause. Reading through those, you can see them referencing known batch issues like split shaft seals or double heat treatment of the fuel pump cyl head which cause it to crack. We did not know about either one of those things until we saw it there yesterday. We may have a 105 trucks which fell into a bad batch range. At least now we can figure that out.
