S&S Diesel CP4 to DCR Conversion Kit Q&A | XDP Tech Tips 

Why would throwing an experimental band-aid fix be the best thing. There are millions of cp4's in operation with less than a 7% failure rate, a failure rate that 99% is due to human negligence.

@@HSKFabrications experimental? You do know this style pump has been used for years in other applications. The cp4 is a complete shit pump. If it was such a good pump then why did ram and gm stop using it? It’s because they know the pump is garbage. It’s funny how so many shit on this dcr pump, but everyone was crying because no one made a pump that would replace the cp4 and now someone does and the cp4 is so great lol 😂. I’ll take my chance’s cause at least if this pump goes out it won’t wipe out the whole fuel system.

@anthonyc993 Experimental to the 6.7 platform. I know it's been around, made in China for years. It's a shit pump in the hands of shit owners. I've been modifying 6.7's since 2011 with zero cp4 failures, I take care of a fleet of F550's with zero failures. It's comical that you think the dcr will not fail, when in fact there have been tons of failures including seizures, which in the 6.7 will spin the crank gear(if not welded) and cause catastrophic damage. We also don't know the long-term effects of a 2-pulse/Rev pump in place of the 4-pulse/Rev cp4 which is timed to the 4 injection events/Rev to prevent high pressure rail harmonics. To me, the dcr is an excuse for the lazy to continue to be lazy since it's touted as bulletproof to contamination. But you do you. Hop on that bandwagon.

@@HSKFabrications I have not read or heard of one dcr failing. You are full of shit. You don’t read to well cause I never said it couldn’t fail. Also you are thinking of the cp4 that can seize and destroy the engine. Some have had great luck with the cp4 and others have not. The pump will not handle any contaminants at all. I have no problem putting a product on my truck from s&s as they sell quality parts.

@@HSKFabricationsmy cp4 failed at 118k with no metal wear just worn out

You might as well put a 15+ turbo on why your there lmao

@brenden4258 turbo new vacuum pump a few intake pipes, down pipes.... its all coming apart might aswell do it right

Should be fine. S&S released a video comparing DCR to other pumps, namely a 10mm stroker, and it outperforms the stroker on the top end for fuel flow.

So in the dcr pump the bottom of the pump where the motor turns it is separate from the pump heads the cp4 pump is not so the cp4!would Gernade and all the metal from the lower end of the pump would send the metal to the pump heads and pump metal filled fuel trough you lines, fuel rails, and injectors it would also go trough the return and kill your fuel cooler. The dcr pump even if it explodes with is less likely the metal will stay contained in the bottom of the pump and not sent into the rest of the fuel system

Watch the video lol

SERIOUSLY

We would advise you to reach out to the installer or S&S Diesel to help find the potential issue as XDP’s F-450 does not sound any different than it did before the installation

​@@XDPDieselwhen ordering a DCR do you need a specific year? Or are all cp-4 the same pumps over the years? Thanks

@@mrglock2313 there is a 2011-2019 Ford 6.7L Powerstroke version as well as a 2020-2022 Ford 6.7L Powerstroke version available

Do they or are they going to have one for the Nissan Titan with the 5 l Cummins?

@@XDPDiesel All years are under one part #
