Bummer the pump took a dive but definitely shows the value of a well thought out DPK. Thanks for sharing.

 

In order to be denied warranty the part installed MUST have caused the damage. Since all it does is splits the feed, it would be a hard sell for it to be denied. Besides, its the guys under the hood who tell Ford what the issue is. Is the fuel clean? Yes, warranted. I highly doubt Ford would add is there a DPK installed check box, especially considering the track record of the DPK and how it prevents HP side damage. Ford would more than likely gleefully warrant a pump over the entire fuel system.

 

2022 F350.. DCR installed. Still lots of warranty left. Sure CP4 could of lasted the lifetime of the truck but now I have piece of mind.

 

Yes.... that's the way its *supposed* to work.

Real world results vary.

 

What is the cost of a DCR pump install? $2-4k? I would rather be on the hook for that instead of $11-14k if Ford denies warranty for found fuel contamination since I have little personal control over fuel quality.

 

I paid $850. For install, so all in it for $2850.​​​​

 

I am excited that S&S has stepped up and provided an engineered replacement for the fragile CP4. I am also happy to see how many early adopters that will help build confidence that the DCR is indeed a robust solution. There are tens of thousands? of CP4's on the road, and by comparison very few DCR pumps, so for me I will sit back a while and see how this goes. I do have a S&S DPK installed on my truck, and the early data looks good for the DCR. Worst case failure for either of these pumps is one that locks up and spins the crank gear, fortunately it seems not too common but we do see that from time to time with the CP4, will we ever see that with the DCR? Too early to tell for me.

 

If you factor in all applications and variants there are millions of CP4's out there, some more successful (6.7 PSD, believe it or not) to less successful (2019-2020 6.7 asymmetrical Cummins pump, VW diesels). There is no guarantee a cp4 will fail however when they do fail they fail big. a DPK is a smart hedge and the DCR looks like a great solution. So far preliminary results are promising and I hope that trend continues.

 

Seems to me that if the CP4 design included a DPK type system at the factory level, the very rare failure of this pump would be a non issue.

It's all the other problems that occur when it fails. A $10,000 plus repair cost is ridiculous for an out of warranty failure of a fuel pump.

But I'm sure Ford saves a few dollars per unit not using it.

 

Have we determined if the DPK did its job? Is the MPROP clean?

 

Imagine the money they've saved by continuing to use it versus designing the fuel system around a more reliable, robust pump. Good for them, bad for the consumer...potentially. They just hope it makes it past warranty period.

Not yet. It will be a few weeks until I am back into the truck

Doing DCR install on my 2020 this weekend, have all the parts, torn down to pull FCV valve, it's fine, but I'm doing the DCR upgrade anyway. I want to eliminate the #1 potential cause for breakdown as I plan to do some long distance trips hauling my Intec car hauler.

 

Makes me wonder what the ratio of production to units failed is.

Might be so small a number it's shocking, but due to the resultant catastrophic damage, it gets a lot of play time with us and others.

 

Better chance of finding Jimmy Hoffa in your backyard than getting that data from Bosch or Ford. Ford did by far and away the best job on the low pressure side fuel system for CP4 equipped US pickups. GM famously lacked a lift pump and dodge's lift pumps have been lack luster going back to the 98.5 VP44 24Vs. But to your point, when they go boom generally is it brutal and catastrophic, no little kabooms.
