Less than 1% of all the 6.7Ls produced. It's across all three brands. Jeez stop with the nonsense.

Click bait for those who can't find reality in data and numbers.

I saw that video the other day - it does have a good perspective that should be appreciated by folks who are willing and capable of doing their own work/maintenance.

With that said, I don't think it's a systemic issue with the truck. All parts have a degree of failures, regardless if it's gas, diesel, or any other mechanical piece with moving parts. It sucks when it's a lift pump in a diesel as the consequences are significant.

I think the real issue isn't the CP4, it's how Ford handles these warranty requests. They have designed the process around first blaming the owner and scouring the vehicle for the slightest bit of evidence to support that claim, even if only marginally supported.

Does Ford encourage the disaster prep kit? Does it void warranty, etc?

Ford covered the warranty repair, but it does take some time for the dealer tech to perform some inspections first. I've heard rear view mirrors replacements due to electric function failures is the most difficult for warranty coverage.

Probably not, but they would have to prove the DPK was the cause of the failure, which would be extremely difficult since it is designed to split the feed into the separate chambers without any reduction of fuel flow or pressure. If anything it would help boost the warranty claim since it prevents damage to the rest of the system.

It shouldn't, but knowing Ford, it most likely will. For me, I felt it was worth the risk of protecting the rest of my fuel system should the CP4 take a dump and installed the S&S kit rather than hope that Ford would honor the warranty if I ever needed it.

I just bought one for my 2022 but havent installed it yet. I can deal with Ford walking away from the CP4 failure and me having to eat it. I can't deal with having to fight for a $12k fix for the whole fuel system. BTW, I reached out to S&S for info on what Ford has been saying regarding CP4 failures with the DPK installed, but so far crickets. That's not reassuring, just saying.
The Ford reps who monitor this board (and FMC in general) being totally silent on all of this is remarkably disappointing as well. I got it, its about $$ and admitting liability, but I've owned 4 PSDs and I expect better. I understand parts fail as I'm a technology manager and engineer, but when the failure of a part causes a chain reaction, that's **** poor FMECA and totally unacceptable, especially when that part/assembly has no way of being accurately monitored.

I would imagine Ford would try to deny the warranty if they saw that a DPK was installed, although, unless they can prove it, they shouldn't be able to. However, we know how that can go... I don't figure S&S will have much to say about it though since they aren't Ford, and I doubt Ford is interested in trying to find out how much the DPK helps if the CP4 does take a dump. However, there is a great video from S&S showing how they have purposefully destroyed CP4's in both pre and post 20 MY trucks and then reinstalled it and ran the truck. The end result was obviously the destroyed CP4 (because they destroyed it on purpose) but the rest of the fuel system was safe and didn't need to be replaced.

I'd say the DPK and additives are the best options we have until someone else comes out with a replacement. Well that and trying to choose a fueling station that hopefully has good diesel... but we have even less control of that... hence the DPK and additives.

Also, for the record, if you are interested in installing after market cold or hot charge pipes, or new intakes, it would be a good option to do it all at once!
