The 6.7 Powerstroke was designed around the CP4. S&S Diesel covered this, and mentioned it that there simply isn't enough space for a CP3. You cannot fit a CP3 directly to the Powerstroke. The best solution right now is to put an additional CP3 pump to assist the CP4. The only total replacement for the CP4 on the 6.7 Powerstroke is the S&S Diesel DCR pump conversion. The diesel fuel's quality isn't the problem, it's the sulfur content. Diesel Fuels in Europe have a much higher sulfur content than ultra low-sulfur diesel fuels in the US. Sulfur acts as a lubricant in the pumps. As you mentioned, the CP4 was designed for Europe. That's why it's having trouble in the US. As for Ford, I have no idea what they've done to make the CP4 work. I've watched a couple of videos, and I think it's just has to do with better water-fuel separators and so on, and different injectors within the pump itself that directly lubricate the cam roller. I think diesel trucks will be fine as companies learn how to work with modern emissions standards. I'm excited to see how the 2023 Fords handle the DPF regeneration process and so on. Edit: www.dieselworldmag.com/diesel-technology/cp4-2-fuel-pump/ This article explains why Ford has fewer failures than the LML Duramax. High pressure fuel pumps require perfect timing in relation to when the fuel needs to be injected, i.e., opening and closing of the camshaft roller. This means fuel also needs to be given to the pump quickly. Ford uses a small electric pump to assist the CP4. Whereas, the LML Duramaxs used a mechanical pump which wasn't able to assist the CP4 sufficiently and quickly. If you have a Ford under warranty, get an S&S CP4 Disaster Prevention Kit. Once your warranty expires, get the DCR pump from S&S Diesel installed. Though with the new generation Ford obviously improved on the reliability.
The reason the Sulfur Content is so low in the #2 Diesel fuel today, is because with the new Emissions Standards being so ridiculously tightened, they started putting Catalytic Converters on Diesel trucks & cars, Well, Sulfur ruins the Catalytic Converters. So they thought, in their small world of wisdom, that lowering the Sulfur Content in Diesel was the best way to solve the problem. And here we are, now the Consumer is once again on the hook for very expensive repairs on their Diesel Vehicles. That's why it is imperative that you run a quality Lubricity additive, Sulfur & Cetene, to your Diesel Fuel. I own a 2015 Chevrolet Silverado 6.6L Duramax Diesel & I run Stanadyne Performance Fuel additive at every other fill up. I heard HotShots is a good one also. I have 208,000 miles on it, just put an Exergy MPROP on the top of the CP4 Pump, $275.00, it stops the metal filings from going past the pump. I see a new pump in my near future though, bout 250,000 is what I'm hearing. If you have a FASS lift pump & the Exergy MPROP that has a steel cage that holds the Dual 10 or 20 micron screens to the MPROP, you are looking at a longer life span of the CP4 pumps, but if the pump does fail, at least you only have to replace the CP4 & not your whole fuel system. I've seen CP3 fail also, it's a Lubricity & Cleanliness in the Diesel Fuel Problem. If we had excellent fuel Filtration & a great level of Sulfur in our Diesel Fuel, these pumps would last at least 500,000 miles.
I'm a diesel tech at a Ford dealer and I see very few CP4 failures outside of contaminated fuel. I'm convinced the filtration is better. Im also unsure of the lift pump pressure on the GM and Cummins. The low system lift pump runs the system at 70psi and that high of an inlet pressure may actually help. Just a thought.
I REALLY appreciate seeing you put this post ! I recently started reading about this entire set of problems and called my local Ford dealership and he said he's not seen anyone having issues with this. I've always added fuel additives in my diesel trucks and hopefully it will be ok.
@@slickmechanical I agree the Ford fuel filters are much better. I still got the DCR and am keeping the factory plastic fuel filters. S&S has a video out about the after market can filters rusting from water in the fuel and causing failure. Stick with the factory fuel filters to help avoid this!
I would rather install an S&S Disaster Prevention Kit, because Ford may deny warranty claims if anything else goes wrong with the engine. Maybe make a video on how the new pump does!
@@tim.prasad03Ford denies warranty for a ton of things. I’d rather be proactive in changing the pump vs Ford denying and being on the hook for a 10K - 15K repair.
I swapped my CP4 to the DCR in my 2020 F250 about 2 months ago. I have seen no issues in drivability but sleep a little better knowing I don't have the CP4 to worry about. My old CP4 had 120k miles on it and it looked in great shape and the screen had no visible metal. My extended warranty just expired (125k) so it was worth the small investment to avoid a large potential hit down the road. I think it makes sense if you are keeping your truck as I am, but if you are always trading things in before or around warranty expiration it probably isn't the best investment. WIth that said, ALWAYS use a quality fuel additive at EVERY fillup. It is just something we have to do with modern diesels in the US.
My local Ford dealership told me the repair bill is around $18K for a complete fuel system replacement in the event the CP4 fuel pump fails, which is why I purchased an extended warranty through Ford for my 2019 F-350.
I understand why you bought the extended warranty BUT Ford will do their best to NOT warranty the failure. They will tell you that in the fine print it states INTRODUCTION OF FOREIGN CONTAMINANTS WILL NOT BE COVERED!!
Mines in the shop right now at the Ford dealership and the price is 12k ...and they won't warranty the S&S DCR fuel pump...I have had them order and install the disaster prevention kit before I take the truck back ...I'm at a total loss on a truck that just hit 89k miles....I'm pissed
This exactly happened to us this month on our 2014 GMC 2500 HD Denali with about 60,000 miles. Mechanic told us this usually happens around 90-100k miles on truck.
you mentioned that the cp4 pump was designed for European diesel. I am currently living in the Philippines and looked up what standards are being used here, since about 75% of the vehicles here are diesel. The diesel in the Philippines is manufactured to the euro4 standards. that should be just fine for use with the cp4 pump. Just for an FYI, the f150 is being sold here as a new truck with the 3.0 power stroke and in the ranger they are using the 2.2 diesel, although it is not called the power stroke. I am in the market for a new truck and I wanted to know what I would be getting into with a f150. now I know. thank you.
It's my understanding that Ford has always had a lift pump which takes some workload off the Cp4 and that helps a good deal. But GM eliminated the lift pump on the LML in 2011 so the LML had to do double duty of lifting the fuel from a straw sized pipe and also pressurizing it for the rail. If you have a 2011-16 LML its a good idea to retrofit either a Fass or Airdog lift pump on it, and then add a Exergy FPV valve to the CP4 to at least save the lines and injectors if it blows. But the best fix is to just put a CP3 in it and a lift pump and your good to go.
S&S Diesel claims to have solved the CP4 pump issue, by creating a replacement, OE standard pump that fits in the space created by the original CP4. They argue the reason it was never changed is because the 6.7 engine was built around this small Bosch CP4 pump and changing it to a larger pump would simply not fit the space or the OE terminals to work with the existing sensors, hi pressure hoses and the like. So they created one, not a prevention kit (which they also have) but an actual pump that fits and works in the 6.7 engine configuration. I cannot confirm or deny the validity of their claim, but it’s worth watching and making your own assessment of the S&S UA-cam video. ua-cam.com/video/hNXIH-JNg30/v-deo.html
GM denied denied denied on the LML. Told the judge in a class action lawsuit the consumers used bad fuel. Oh yeah say how so GM when your owners manual states to use low sulphur fuel. They could have saved themselves millions of $$$ had they told consumers to use fuel lube additive. I'm waiting on my payout GM for what you owe me! My LML CP4 failed after a mechanic put in a Exergy FPR to catch a failure. I suspect air got into the pump. Kaboom! I suspect a Ford because of an additional pump and less chance of air getting into the fuel is why they have had fewer issues. I run a fuel lube additive in my F250. Plus I have the S & S prevention on it.
THEY FAIL ALL THE TIME .THERE IS NO MONEY IN FORD PUTTING BETTER PUMP IN FOR THEM ITS A MONEY MAKER FOR FORD ESPECIAL IF THE WHOLE ENGINE FAILS AT 23K PLUS
My 2011 6.7L engine runs a lot better and quieter with the S&S disaster prevention kit. Not sure why except maybe more fuel is available to enter with bypass kit. I think one of S&S videos explained that. I forget all the details but it does improve the torque at higher RPMs before falling off.
If you can't afford the new S&S pump get the disaster prevention kit and run fuel additives that increase lubrication. Hot Shot Secret and Archoil are Good.
It was funny you never mentioned that Ram issued a factory recall on 2019-20 and replaced all cp4 to cp3 at no cost. Maybe ford doesn’t want to stand behind there cp4 failures because the customer will pay for it if they want there truck. Customer service
Everything is great in a classroom setting but honestly in the real world testing the multiple variables in fuel it’s a poor design and the facts are Bosch will be replacing people’s engines or something like that after the lawsuit is over absolutely poor engineering from a logical standpoint! Life isn’t in a controlled environment water gets in diesel that’s a fact of life has been for 90 years 🤣
Ford should get away from the cp4 pump all together and go to the S+S pump . I don't believe you when you say that there are very few 6.7 having cp4 failed. I recently had mine go out at 58,000 miles . Totally unexceptable , at the least ford should be installing the disaster kit to prevent contamination of the complete fuel system . $15,210.63 to get it back on the road with only 58,000 miles is irresponsible of Ford when there are bullet proof pumps that are available after market . I've said my pease but it doesn't make me any happier .😂
Mine was deleted and the cp4 still took a dump on me. And I stay on top of filter changes, additives every fill up and never let the tank get below a quarter of a tank. Word to the wise, if you can afford it, get the S&S dcr pump or bare minimum get their disaster prevention kit.

according to Ford any CP4 failure is contaminated fuel and not covered under warranty. Ford is shit.
I ordered the S&S DCR pump kit. They just started to ship out on the 15th. It’s not a cheap system, but way cheaper than a whole fuel system.

Swapped out my cp4 to the New S&S DCR pump. It's been over a year and around 10.000 miles. So far, it's been great.

The Rams from 2019 and 2020 had the CP4 recalled and replaced with a CP3. I have a 2020 2500 Cummins, and it’s had the recall done, no CP4 on that.

your warranty is worthless. any CP4 failure is caused by contamination according to Ford and is not covered by warranty.

A CP3 will not fit like it did in a Ram. And there aren't nearly enough other styles like the DCR to replace all the CP4s in existence.
Because if they changed it they would have to admit there is a problem with it
