once fuel lubes the cp4 bearings…the fuel passes thru a return filter…then the fuel goes back to the tank…where it is filtered by the two stock filters before returning to the engine.
the oem model has fuel going to the cp4, then from the cp4, the fuel goes to the injectors…any metal wear from the cp4 will carry particles to the injectors in the oem model.

It doesn’t. The only thing that can save your injectors from a component from that side of the pump failing is an upgraded MPROP from Exergy. The other kits only protect from pump crankcase component failures.

The more I read about S&S the more I think the DCR pump is the key to bulletproofing the fuel system on a 6.7
theyve had decades of engineering for major OE’s including Cummins. Have some of the best fuel component research labs and engineers.
Once I get remotely close to warranty expiration I think the DCR is the key to bulletproofing the fuel systems on 6.7s
would eliminate it’s Achilles heel without losing the amazing performance that comes along with the PSD engine option…….
hmm…..

I’m also looking into replacing the water separator and upper fuel filters with the H&S Motorsports Cat/Baldwin conversion kit. That allows the use of semi-truck style spin on filters for the upper and lower.

I’m thinking along the same lines. A Stanadyne DCR is almost bulletproof. I’ll make the decision once I hit 90k.

I don’t want to lose the performance of the PSD by going with a gasser…..and I think if you time the swap appropriately you can eliminate some of the weak points pretty easily to not leave yourself with an out of warranty cp4.
In short….I think if you have a current cp4 failure or you get up in mileage with an expiring warranty then the DCR makes complete sense for a couple thousand.

Between this one and @Ltngdrvr's failure I think that I will plan on when my 2023 warranty is about up that I will swap out the CP4 for a DCR pump, it is cheaper that an extended warranty.

youd have to ask them what changes were made they put a lot of engineering into them and I’m sure they’d explain to you

you need sometjing sooner than S&s will have the new pump ready but would it have been something you considered?

No, I would have to pay out of pocket for it, warranty wouldn't cover it because it is not oem parts or equivalent.

i feel like I would be half tempted to have them do the replacement so you get the whole new fuel system but then still swap the pump on my own after going thru a cp4 failure
then you’d have all new stuff and nice pump in the DCR while the most expensive portion and labor was still covered by ford.

The screen shots bellow are from one of their YouTube videos, in response to the kit not being available for 2020+.
