Powerstroke CP4

Just want to know what folks have done regarding their fuel pumps. Please tell me your experience. I'm considering going preventative with either the S&S disaster prevention kit or DCR replacement. Thanks.

  • Thanks StirCrazy. Yes I'm in the USA, and my truck is a 2017 F350 which I plan to keep for some time. All that was in my signature in the old forum. Only 44000 miles, but with retirement approaching I expect to increase my usage, some of it in Canada. I would be interested in seeing those videos.

    Others care to relate your experiences?

      I will see if I can find the good ones again, they did wear scar tests for different additives and cetane tests, the one I got was the second best for the lubracation, the best one isn't available in Canada that I have found.  you have the same cp4 as I do, I think it was 2020 when the first updated one came out and then in 2024 for the 3rd advancment.  I would for sure do the desaster prevention kit, make sure you buy a second generation kit not the original.  I am even thinking of putting one on mine, but not because I expect it to blow, but maybe more of a just incase 🤣  I do also plan on visiting the USA again when the prresent situation is over and that would mean using USA diesel so might as well be safe.  

      here is a good video 

      additives compared

        Can we become the 11th province? Fix the diesel plus🙂 a few other things.

  • depends, if you live in the USA then a desaster prevention kit most definatly, I would do a new pump when the pump actualy packs it in and you need to get one.  in the mean time a good additive like archoil AR6500 will give you the lubracation and cetane USA diesel lacks. As for the DCR it is still new, I believe it was introduced about 2 or 3 years ago and there is not enough data for me to be able to recomend if it is the way to go.   also the year of your CP4 makes a big difference.  there are 4 or 5 generations of it out and each one better than the previous.  since you were talking about the dcr replacment I am assuming you have a 6.7 powerstroke, but the year will tell you which generation of cp4 you have

    the issue isn't the pump its self, but the diesel we use in north america, perticulary in the USA.  in Europe they have a less than 1% failure rate, in the USA that is up around 8 or 9% and in Canada it is back down around 1%.   the reason is the lubricity standards in european fuel, the USA didn't follow the same levels and hence is wearing out more pumps.  Canada did follow the european specs for lubracation.  I am in Canada and I still run a lubracation additive, make sure its a good one, most are not good at all, if Ican find the testing videos again I will post them for you.  the other issue both USA and Canada have is wedidn't follow the cetane requirments of their deisel also, hence we don't get the fuel milage they do.  so I add a bit of that back also.
