I know this is a Chevy forum....But I gots ta know....Why in the F%^! is Ford still running this disaster in their 6.7L PowerStroke engines?

Because as Ford states “Quality is Job #1.”

Who's really had a failure? Sure you see it happening here and there on the forums, but have you seen one?

I know many people with CP4s including hard use trucks in oil and gas development, mining, construction, agriculture, etc and I've never talked to anyone with a failure.

Moreover, Bosch supposedly made some changes to the internals improve reliability in them, so maybe it's not so unreliable.

I got 11.5 years on one and it's heading towards 15. Gotta run Opti-Lube and a lift pump to help your cause.

There's more 6.2L motors grenade in the last year than CP4s in the last 10.

There were enough CP4 failures in Ram's that Ram recalled all their 2019 and 2020 trucks and installed and updated CP3 and continued production with those CP3s.

have you seen one?

Yes....But more importantly, as stated by @AEV.Nate, the government has seen a few .... https://static.nhtsa.gov/odi/rcl/2021/RCRIT-21V880-5163.pdf

There have been enough to result in class action lawsuits.

There have been enough to result in companies producing kits to avoid the contamination from failures.

I don't deny that you haven't had an issue....And you have stated that you use an additive. But think about this....From a perspective of a consumer, should they have to use/know about using/be required to use an additive to prevent a failure? The answer is no.

Would your pump have lasted this long if YOU didn't use an additive? We can't say.

99% of diesel trucks on the road have never ever used an additive or a lift pump. Especially the fleet vehicles. They get rode hard and put away wet. I would say Ram and Ford outpace Chevrolets 5 to 1 in heavy civil duties that I'm around frequently. Almost everyone I know runs Ram because of the Cummins. Never heard of a CP4 failure.

We're running water to a frack in Dakota now and it got shut down for 2 days cause they delivered crappy diesel fuel to the frack pad and it had to be replaced cause the equipment wouldn't run. There's millions of HP sitting on 10 acres pounding through millions of gallons diesel right now.

There's every brand of equipment and diesel motor you can think of and they probably will use more diesel in the next 20 days to frack these wells than this forum will use in the next 10 years. Ain't anybody treating 1,000,000 gallons of diesel and every Ford, Ram, and an odd Chevy are fueling up with the same bulk diesel tanks. It's well below 0F and we're running water 20 miles away. Most of this equipment won't get shut off for the next 20+ days or it would freeze up. Ain't nobody sweating a CP4 failure.

These failures are rare and the only people getting anything out of a class action lawsuit are the lawyers. That's just how class action business works.

They only had a CP4 in Ram's for 2 years. They recalled all of them. While I agree it's not common, but it was enough to cause a recall. When the CP4s would fail in the Ram's they would have to replace the entire fuel system. Tank, fuel lines injectors and pump.

I don't know how common this is with the GM trucks, but I heard they also use a CP4.

I posted about the GM recall a while back. Most owners won't get shit out of it, cause it doesn't even cover all years.

Some time back, my service advisor said that the few trucks they'd seen with grenaded fuel pumps GM warrantied them under their customer satisfaction campaign.

A buddy of mine works in the gas industry, he’s had 3 total failures in about 10 trucks in his fleet over a 6-8 year period He had one covered under warranty, the second and third he paid for full fuel system rebuild, last I talked to him he was done with duramax and phasing them out across this fleet.

For whatever reason, the CP4s in the LMLs will and do fail…and it’s a nasty deal when they do. I tend to agree with you though, fail rate on lifters are much more common

When I sold my rig to my boy for -$20k, I made him buy a 5 year warranty that costs him about $800 per year. That'll get him 15 years on that rig. I don't think the one on the left will be serviceable in 15 years, cause it'll cost too much to replace all the crap parts they put on em.

Lift pump, lubricant, and good fuel (which you really don’t know ultimately) will go along way. A disaster kit is pretty cheap insurance and a CP3 conversion is the ultimate solution although the most costly. I bit the bullet on my LmL and did the conversion, likely overkill but simply didn’t want the risk pulling and hunting remotely.

Per the original post, @MrScottly - given the options available, it’s certainly a head scratcher. Unless they’ve got contracts or inventory to burn or maybe they have run the numbers and know the % of failure will be on owners vs warranties?

Sounds plausible. Still a headscratcher, from a customer service and image perspective.

There is also an inline screen made to catch all the CP4 hard bits before they get into the rail, injectors, return line, and tank.
