I would be lying if I said I wasn't interested in this deal but will probably let a few kits get out there and get some feedback before doing anything. Definitely won't be adding a DPK though.

I do keep a close eye on the low side fuel pressure to make sure the HPFP is continuously fed a healthy dose of clean diesel.

Just signed up on their page here,

To be notified when it's available. There is also more information on the DCR on that page.

I'm going on 102k miles on my 2016. I've been using the additive K100D+ since new with every tank, through all seasons.

But IMO, having S&S's DPK is like having insurance on your truck, in the aspect that you hope you don't need it but if you do, it's there and you can use it. Kind of like in the concept of having a concealed handgun as EDC or having a non-expired condom if the opportunity presented itself, that you rather have it and not need it, rather than need it and not have it. I fall on the side of having it and not needing it. But to each their own; YMMV.

As to waiting for another company coming out with another HPFP option for the 6.7 Powerstroke, good luck with that. The 6.7 Powerstroke was introduced in late 2010 for the upcoming new designed Super Duty line for 2011.

S&S Diesel are the guys who originated the DPK kit in 2016 according to this article:

https://www.dieselarmy.com/news/ss-d...p4-bypass-kit/

My point being is that S&S is going to have the market cornered on this pump from Stanadyne. I'm sure there's a patent involved along with a business deal as well. I'm sure there's internal modifications to make this work with the 6.7 Powerstroke.

S&S has made CP3 conversion kits for the 6.7 Cummins and for the Duramax 6.6s. If there was room for the CP3 on the 6.7 PSD, S&S would have done it already and called it a day.

So I'm going to go out on a limb here and say that if someone was to do their own fuel pump conversion for our trucks, they'd have to pay S&S to use their kit. Unless there's another pump out there... But for my money, when it's time, I'm going with S&S because these guys do their homework and they are the pioneers.

A little off target, but kind of like Glock with polymer framed handguns... I do own a Sig and a Springfield but I own mostly Glocks. Sorry for the hijack...

I pay enough for insurance as it is, I don't feel like having another useless policy...

JK I'm sure it is a great product. Just not for me, and at this point I'd replace all the injectors anyway. I really don't think it's as big a issue as the internet makes it seem. Having said that, I've never had one fail, maybe I'd feel differently if I had.

I was referring to waiting until a few DCR kits are installed. I agree with you that at this point no one else is coming out with another kit.

I agree, but I don’t have any Sigs. I do like my SA and Glocks though…

My new to me 2015 F350 has 247k miles on the odometer. The gooseneck ball looks very used and even has some grooves in it. It was a Texas truck with destinations in Arizona in its GPS. I can only guess is that this truck was used to tow something heavy long distances. It also has a layer of brown dirt on everything that they could not easily wipe down. I've found it under the carpets, in the A/C vents, in the seats, etc. So I have no idea on the history of this truck. With that in mind, I think the S&S DPC is a good investment. I ordered the kit and had it in hand before I took the fuel regulator off as if it had debris on/in its screen, I was going to have to replace the CP4 pump. Luckily, it was clean. Does that mean it has not had a failure, that it has and the CP4 has already been replaced? So no, the new S&S pump is not what I need at $2k, unless/until my current pump fails. It's nice to know I now have an option.

I also replaced the cold side turbo pipe. There was nothing wrong with the one on the truck, but I'd rather have the metal one than waiting for a possible random blowout.

All good... I'm for having the kit on, not installed yet but soon, and if my CP4 were to fail, I know I could recoup and sell my DPK kit as I wouldn't need it with the DCR, plus save all the lines, injectors and rest of the fuel system components.

I see you're just being cautious with wanting to see someone here have it installed. But you would be replacing more than injectors if yours schitt the bed; count on injector lines, the fuel rails and sensors, not sure on the return fuel line back but I'm sure you'd want to drop the tank to get all the metal shavings out and make sure all the fuel lines are clean too.

Hell, I hope my CP4 doesn't ever go and I'll keep changing out THE DPK kit filters... But it's nice to know there's a more reliable HPFP out there that doesn't require a filter to protect the fuel system in case it did fail.

It's either the original CP4 or if it was replaced because of failure, I'm thinking the new pump comes with a new fuel control actuator (control valve) as the one from the failed pump would have metal shavings in it.

My understanding is, if the CP4 fails, everything from the pump to the injectors needs to be replaced, so yes, the FCA should be replaced as well. It does make me wonder as with 247kmiles, the FCA screens looked very clean. Maybe the filters have been doing a fantastic job! The vacuum pump was leaking, so there was a bit of oil all over the front of the engine. Hard to tell if it was the original or if the CP4 had been replaced. Oh, and I found a broken piece of plastic from the cold side turbo hose laying on the top of the engine (below the intake), so I'm guessing that one already failed and was replaced with another factory ford hose.

I'm no expert or have experience with replacing the CP4.2, but it appears to come with the FCA (control valve) on it already when purchasing a replacement. That's all I meant.

As to the CAC cold pipe, that could very well be the case.

I forgot to mention that I monitor the DFCM pressure at the HPFP on my iDash, as well. Truth be told, I run my filters out to the recommended change interval of every 3rd oil change. I let the truck tell me when to change the oil, usually by 7.2k miles, so the filters get changed by the max of 22.5k miles.

And honestly, the pressure doesn't drop by much at the end of the service life of the Motorcraft primary filter in the DFCM (primary pump).

Matter of fact, this last recent oil change with fuel filter set change, the primary filter looked pretty good. I believe I am getting good quality fuel at the local carwash chain here that I go to. But I still use the winter dose of 500:1 of K100D+ every tank as well as Pittsburgh Power's Max Mileage FBC.

I agree that I've never seen a pressure drop, I always keep about half a tank of fuel in it also. For me I just like to see what's in the lower bowl. Helps me validate the stations I've been using and would allow me to make a correction sooner rather than later if I were to see something alarming.

Hopefully this DCR is a drop in reliable solution. I'd rather spend an additional $1600 and eliminate the problem forever versus put a bandaid on it that hopefully cathes all the debris if it fails.

Hopefully we start hearing some feedback soon!

Going to stick with the Gen2 DPK.

Reason being that it DOES work, there appears to still be a lot of misunderstanding on how the DPK functions. The way it is designed there is absolutely no way a failed pump can contaminate the rest of the system.

The ability to drive the truck with a failing pump and increased pump flow at 3000rpm+ is an added bonus.


It is also great for someone who doesnt use a fuel additive and buys fuel from rural fuel stations.
