6.7 Powerstroke cp4 fuel system replacement

We show how to replace your cp4 and related fuel system components after the dreaded cp4 implodes.

[@irredeemabledeplorable5227]

I sure wish that I didn't have to go looking....but, that said, this is, HANDS DOWN, one of the BEST 'how to' videos that I have ever seen...I've shared it plenty already ....and kudos on the v8 mud dobber nest.

Yea, I should have removed that nest sooner to avoid catching flack over it. Thanks for the compliment and watching.

EXCELLENT video! Doing a little bit of studying here. I’ll be replacing the CP4 on our 2017 F450 wrecker this week, got towed in behind our (thankfully) already CP3 converted RAM wrecker for a lack of power, then died while idling. Fuel filters are full of metal. Trying to tell my boss (a retired Ford master tech, did most of his work on 6.0s) that you can’t just replace the pump without having a repeat failure, as I’ve done this job on a couple LML Dmax trucks from my days at the dealer. Hopefully this hammers that fact home, as much as it sucks for the downtime of the truck and profit losses, it beats having to do everything a second time.

[@Viewer899]

I use Archoil fuel additive in my truck. The research I have done says it will greatly improve the life of the CP4 pump.

[@AutomedicGarage]

@@TheShadeTreeMechanic-k9b yes it will however the pump design is the true flaw, it’s a very aggressive cammed pump

[@williamself6241]

Very well done video on this project! Thank you. What did you see on the computer to follow this repair? I have 2012 and died on the road with no start, p0087 code. I thought cp4 for sure, pulled vca/vcv on top of cp4 and clean as a whistle no metal so I replaced it, also looked at the PCV on driver side fuel rail also clean as a whistle, replaced it as well. Only getting around 300psi actual with almost 5000 desired. Also put gauge on low side before engine mount filter and had 54psi. Not sure where to go from there. Any suggestions would be greatly appreciated. Thanks

[@royallean1634]

Mine is doing the same thing

[@AntiStock505]

Sounds like a cp4 failure. I have seen some fail without sending metal through the whole system. There is a good right up somewhere on the forums about it. I’ll try and find it.

[@Hvgyjggds]

Was it fixed? Have same issue here

[@jasonhansen6632]

my 2015 f250 needs this done to it, CP4 blew out about 2 months ago w/280K (yeah I drive a lot--DFw to Houston to Austin at least once a week sometimes twice). Luckily, I have my previous truck-2011 Ram 6.7 for back up. I am wanting to do the DCR and new rails/ injectors/lines etc, but I am wondering why it is necessary to drop the tank and clean it? with a new lift pump and the disaster prevention kit and both of the new stock filters, how would any of that glitter make it past those three filtration points? Also, with 280k, should I also replace the turbo coolant fittings or possibly the turbo too? I would hate to have to go back in there within the next couple of years for something I could have done easily while in there.....

[@juanalaniz3577]

My 2015 f250 just crapped out on me as well. Has about 170k miles

[@LTDan-pk3mx]

Amazing video! Question.. What are from not so bad to real bad scenarios of accidently putting gas in and running it till it quit, Then pumping gas out filling with diesel starting and running but now it is in limp mode. Thanks again!

[@AutomedicGarage]

Gas will ruin the cp4 fast. The fuel itself is all that lubricates it

[@salinasvalleytowing7842]

Really good and detailed video. Thank you! What scanner do you recommend for a 2017 f550?

[@AutomedicGarage]

I like autoenginuity(what I use)but I will try out the cheap one I just tried out on a 6.0 and made a video on it. It worked great on the older trucks so I’ll make one on the newer ones.

[@travisthompson3700]

[@AutomedicGarage]

Yea I know, it was gone in the end. Just didn’t get it in video.

[@mikemangino854]

So I'm getting ready to do this on my 2017. My mechanic tells me since my truck lost weight I won't need to reprogram the new injectors. Is that correct?

[@evolburd5768]

had to do one of these where the last guy didnt seat the injectors correctly and 4 of the injectors were seized with carbon. that was a fun day.

[@billycrocker6811]

What programming software do you guys use? I have this very issue on a truck right now and would like to get software that will work on my IPAD Pro. Any thoughts?

[@ethanpaul3689]

Hate to think about the possibility of mine going out, but at 255k I figure its bound to happen at some point. I would like to do it myself but my expertise doesn't extend far beyond repairing tractors and bigger equipment, which is typically much less complex than my 6.7. Just general ballpark if you don't mind me asking, what did this fix cost the guy? The workmanship and quality you put into your work would definitely make it worth whatever the costs associated with paying you to do it would be.

[@AutomedicGarage]

It was around $7500 for everything

@@johndixon1992 yes for sure

[@noonesbusiness8009]

What’s your honest opinion on the disaster kit? Maybe I’m wrong but I just don’t see how a filter can stop all that debris pushing at 29k psi. Maybe it will but I’m a little skeptical. Obviously if the DCR is as good as they say it is this is the best solution. Let me know your thoughts. By the way that was an extremely good video on the process. Very thorough and the best I’ve seen on KZbin.

[@AutomedicGarage]

DCR is better money spent than the disaster kit

[@juan93862]

So if you flush all the fuel lines and fuel rails and flush the fuel tank just replace the pc4 pump and injectors.. it works? Or there is not way to skip to buy fuel rails and fuel lines??

[@AutomedicGarage]

You have to replace everything if there is metal in your FCA. I clean the tank and the supply and return from the tank but everything else gets replaced. There’s no way to clean the fuel logs. There is restriction passages within the log that you cannot clean. Hard line are 1 time use anyway and come with the new injectors. There’s only one way to do this job right and that is replacing everything other than hard lines from tank and fuel tank itself.

[@gabewall7381]

What are your thoughts on the DCR conversion from S&S? According to the tests I’ve seen even if that pump dies down the line it has the advantage of not contaminating the whole system and it performs the same as the CP4

[@AutomedicGarage]

I’m on the same page with you, I want to get my hands on one. I like it.

[@gabewall7381]

@@AutomedicGarage Exactly. I’m a huge 6.0 guy, love working on them, love the platform in general. But the DCR coming out along with the newer steel piston motors greatly increases the likelihood I’ll own a 6.7 eventually

@@Ceja-gc5hw I charge $3500 labor which is cheap compared to most. Contamination kit is around 5k add around $1200 to upgrade to DCR pump which I highly recommend. Ford is anywhere from 10-14k for this same repair and I can’t explain why people get different prices from different dealerships cause the book time is the same regardless.

I don’t understand how you can explain some thing like how to remove the high-pressure fuel pump gear, and then not show us how to do it. Because I’m hitting it with a punch and it’s not coming out.

[@AutomedicGarage]

I explained how to do it. I use a punch and a 2 lb mini sledge. Works for me. If you don’t care about the pump put a air hammer on it. I guess you didn’t think of the fact that it’s a hard angle to film while I swing a hammer at a punch or did I need to show how to swing the hammer?

[@jimm2442]

After doing any amount of research on Bosch CP4 high pressure fuel pumps why would anyone buy a vehicle with one? Why does Ford continue to use it? Both GM and RAM no longer use a CP4. GM quit using a CP4 in 2017 and switched to a Denso HP4. RAM went to a CP4 in 2019 and 2020 and after mass failures are now recalling those trucks and switching back to a CP3. Do truck buyers blindly purchase without any research? I don't understand. Ford is great if you make money fixing the garbage they make.

[@AutomedicGarage]

The 6.7 PSD was designed around that cp4. Nothing else will fit in the valley of the 6.7 but the cp4. That’s why you can’t use a cp3. I have a lot of 6.7s come in with 300k+ miles on original pump. There is another option now which is the new DCR pump.

[@jimm2442]

@@AutomedicGarage I understand the space limitations of the 6.7's valley and non available space for a different pump. My question to Ford (they won't answer it) is why did it take the aftermarket to manufacture a replacement pump? Why did Ford Motor Company not do it? Would that admit fault on their part? I am a retired mechanic with 35 years on the job and your video is excellent and I'm sure will help many unfortunate enough to own a 6.7 with this issue. Thanks for responding I appreciate you and the information you kindly provide.

[@tprice3450]

I'm one of those who has 340K on a CP4. I put an SPE disaster prevention kit on at about 90K when i made some improvements that reduced vehicle weight and created more space in the engine bay, just for the peace of mind.

Motor was designed around that pump before ford,dodge or GM knew it was problematic. Problem is GM and dodge had room for other options while Ford didn’t till the DCR came out.

[@armandomaldonado1559]

Why would you put the same type of pump? Then worth it darn. You should have gone with the new version. You wasted all that time you're looking for more contamination. Or do you want to have problems all your life?

[@AutomedicGarage]

If you would have paid attention and noticed I run a shop. It ain’t my truck. The customer brought his parts in and wanted them installed. I recommended a DCR pump and he said “no I’m good with that” I don’t give parts away and I can only do what the customer approves. And for what it’s worth I have a ton of customers with over 300k on their factory cp4. Is the dcr better, yes but like I said it ain’t mine. Lose the ego.
