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. T...

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
Can we become the 11th province? Fix the diesel plus🙂 a few other things.
Spoken like someone who has no idea what it costs to live in Canada….
Trust me, fuel additives are a way cheaper option to not get taxed to death, on top of a weak dollar and chitty government run healthcare.
Or just move to Canada and see for yourself.
hows your health care doing you? ya we pay more taxes and a cost of living is higher, but we have more open space 😉 we don't have to pay for heath care and after hearing some of the horror stories after the obama care was restructured and how much some people are payign now just boggels my mind. I have a cousin that is a nurse in texas and listining to her stories changed my mind about moving to the US years ago. there are good things don't get me wrong, but there are also not so good things, like any other place.
PS, their diesel isn’t speshul up there just because it costs more….
the lubracation package is better, Cdn diesel follows the eurpoean spec for lubracation, to bad we follow the USA spec for Cetane though🙄
I’m sorry you have a situation that is preventing you from visiting the US…as odd as that may be to add to a discussion about injection pumps.
it is just a fact, when this is done and I can go camping in washinton, oragon and other places again, I will be burning USA dioesel with lower lubricity, thats how it applies to the cp4 pump. so I will be using my lubracation additive religiously down there. Up here If I miss a tank or two it isn't a big deal.
since you don't get it here are the facts for ya 😊
"CP4 Failure Rate Estimates by Region
- United States: ~5% to 9% (some sources cite up to 1 in 14 trucks)
- Canada: ~1%
- Europe: < 1%
Key Factors Behind the Differences
- Fuel Lubricity (ASTM D975 vs. EN 590): The primary cause of higher failure rates in the U.S. is the lower lubricity of Ultra-Low Sulfur Diesel (ULSD). The CP4 was designed for European EN-590 diesel, which has higher lubrication properties (460-micron wear scar) compared to the U.S. base standard (520-micron wear scar).
- Canadian Fuel Quality: Canadian diesel generally adheres to European specifications for lubrication, resulting in significantly lower failure rates compared to the U.S..
- Pump Design: The CP4 relies on diesel fuel for lubrication. In low-lubricity environments, the cam and lifter components in the pump can fail, introducing metal contamination into the entire fuel system.
