The disaster prevention kit does nothing to extend the life of the HPFP. It only protects the injectors and rails and whatever components that receive fuel after the HPFP. Only way to extend the life of the pump is to be sure it's well lubricated with some type of fuel additive.
And not recirculate anything abrasive through it.
I've read reports that Disaster happens to as many as 1 out of 100 trucks. Pretty low percentage. But there are a lot of trucks out there and I've hit boxcars on the craps table
All this DPK kit talk is great and the idea is great, but my understanding of it while in their early years is they only prevent one type of failure, not both failures that occur in the CP4.2, please correct me if I’m wrong, it is why I was not really for them due to this

Being a Newbie, I do not know what you mean by both types of failures. Please explain.
From what I have gathered the DPK keeps the unfiltered fuel from going back through the Pump. So hopefully any small particles are caught in the filters before they are run back through.
It also protects The rest of the fuel system from damage.

Coupled with the Good fuel filters, to remove water and air. I believe you have severely reduced most of the causes for failure.
Running a lubricity additive has been a given since they came out with the new fuel. I've been running B-11 since the 1990's sometime - when it was available to be delivered to the house.
I order B-11 Premium diesel.I have a water trap filter and a 2 micron filter on my storage tank
I always wonder why Schaefer's is never included in the lubricity additives tests. It seems pretty popular in this area. A lot of owner operators swear by it.
When I buy at a station, I always try to add some lube. White or gray Power Service, Standyne, Hot Shot, Schaeffer's, Ashless 2 stroke oil, OptiLube
OptiLube, Standyne and Schaeffer's are my go to's. I usually end up with Power Service - Just because I don't get out much and forget to be prepared when traveling
Is there not a filter before the pump than another one after? If that is the case than how would unfiltered fuel go through the pump?
With all these problems with owning a diesel truck we should all sell these before they explode.

I have heard several times over the years that merely installing that kit does not remove enough contaminates from the system and can be the cause of recurrence. The shops that do it right do more cleaning and/or replacing.
I would not have bought a CP4 if the DPK was not available.
We were actually only looking for a low mileage , rust free, 2007 LBZ . Got frustrated looking and bought the next truck we saw. The banker sent us the truck and said it was priced out the door, lower than their loan value

From what I understand the OEM system does not return to the tank. The return connects to the wrong side of the filter. So whatever miniscule wear particles are immediately reintroduced to the High Pressure Pump.
This is what the DPK eliminates.
We have had just about all diesel vehicles since the 1990's and have logged over 2 million miles combined. Mostly problem free miles. Except the 2006 Jeep CRD - that's been a wallet eating nightmare. But most of the Jeep's issues are electrical and expensive timing belt maintenance

Okay I saw this article from a search on Bing about the Bosch CP4.2 in Diesel World June 2019. I had to buy the June 2019 mag because I wanted to read the whole article. I tried sharing the pages with the forum here but I had to take screen shots in order to post here.
I did this on my phone so i could do screen shots. Let me know if you guys can read it. Hopefully they are in order. Enjoy...
