Ford 6.7L Powerstroke Fuel System Failure | Everything You Need To Know

[@JohnImperato]

I change my fuel filters in my 2019 Ford f350 powerstroke every 10,000 miles and my oil every 7500 miles religiously. I haul with the truck and currently have 220,000 miles. But keep running into people who tell me I WILL have a fuel system failure. Not if but when! I was glad to hear a positive outcome from you. They all told me to install a disaster kit.

[@Theencouragementstation62]

Same here, 2018 F250, change fuel filter every other oil change and just now at 188.000 miles I am getting a message P0087 code came (Fuel Rail/System Pressure too low) Sent the info to a buddy of mine with lots of experience on diesel trucks who explained to me that on my code data the Commanded fuel rail pressure A was 54072.57 inHg and the actual Fuel rail pressure A was 46341.59 inHg giving the message of low pressure. I am now waiting for a local mechanic to take my truck in for inspection but its going to take a couple of weeks until he is open, I decided not to drive it until I can be sure of the HPFP is bad and hoping there is no other issue with the rest of the system. Maintenance is my priority, but I am not sure yet on the S&S CP4 upgrade or keeping the original ford pump, getting mixed reviews is driving me insane. My mechanic also advised me on the upgrade to S&S… I am plan in keep this truck for life so any advise would be helpful at the moment. Great video by the way even for a regular diesel owner like me.

[@jdecker89]

@@Theencouragementstation62I’m curios. What was the outcome?

[@jezreelkirby1988]

Yes what was the out come

[@Webedunn]

Your 2019 shouldn’t have a CP4. I believe they were from 2011-2016 but check. The Duramax discontinued them in 2016. I took my CP4 out at 190,000 miles and I took it apart and it was in GREAT shape but it wasn’t going back in….

[@Webedunn]

@@Theencouragementstation62DO THE CP3 CHANGE! It’s much easier on the Power Stroke than mine on the Duramax. It WAS TERRIBLE! However I now have the tried n true S&S CP3 with a FASS lift pump and it’s impressive. Get a good cold air intake, delete the DEF & EGR and your truck will be a BEAST!

[@paulmaxwell8851]

I think it is already established that the Bosch CP4 high-pressure pump is not suitable for North American diesel fuels, and Bosch engineers have confirmed this. It was the wrong choice. Note that the CP3, fed the very same fuel, has had no issues. It's unfair to blame owners, many of whom have worked very, very hard to avoid catastrophic failures. Unfortunately, although diligent maintenance may help, nothing can guarantee you won't be stranded in the middle of nowhere when the pump finally disintegrates. These pumps are a disaster.

[@diesellady1]

I agree 100%. But there is hope. S and s diesel has made a kit with the DCR pump that will not fail. Really!! It’s the cure we all have been waiting for. Unfortunately, the dealer will not sell it or install it cause then it’s fixed and they don’t keep making money! “)

[@paulmaxwell8851]

You are spot on, diesellady. A friend spent just over $11,000 to get his truck back on the road after his Bosch CP4 injection pump disintegrated. What did the dealer do? Installed another CP4!!! It's only a matter of time before my friend is stranded in the middle of nowhere, AGAIN!

[@sutherlanddieselperformanc4140]

@bret9741 so if I’m not mistaken, as I don’t own one, I believe the 6.7 ford does not have a water in fuel light either. Which means you will never know that you have water in your fuel till it kills the CP4 pump and/or injectors. But they can see the WIF count on the scanner. Just insane, right??? 😢

[@mikeadams42]

@bret9741you forgot to mention that the dodge also has the same problem. At work we had 5 different trucks go down in the same week. 3 on the same day. All 5 trucks got fuel from the same location, dodge claimed 3 had contaminated fuel and denied warranty claim. So imagine spending nearly $300k on trucks, then spending almost $30k 17 months later to fix them. Kind of bullshit, isn’t it???

[@lanehammer]

I protect my 2016 second generation 67 with Stanadyne with lubricity .. Yes, it is a real additive and 5 gallons will treat 5000 gallons of diesel .. Can’t find it on the store shelves generally it’s a special order kind of item from smaller, obscure places that carry it .. I also have an SPE disaster prevention kit, which by their tests and claims proves that you can keep metal from a damage CP4 from entering the rest of the system.. Eventually, it may take a class action lawsuit, or some kind of concession from Ford I’m not gonna hold my breath .

[@BryanMecklenburg]

I appreciate all the knowledge you shared in this video. I only wish the people at Barber Ford had even a fraction of your knowledge. I took my truck in recently. It was misdiagnosed twice for a total of $3500 (fuel rail etc.). On their third try, they figured it out. Over five weeks later, I finally got my truck back. I laughed when you mentioned in the video a dealership should eat the cost of misdiagnosed repairs. My dealership did not feel the same way so I had to explain why I should not have to pay $3500 PLUS another $11,000. Thanks for making videos like this. Not only are you helping to educate end users, I am sure a lot of mechanics find it useful too.

[@DannyHollis]

From a 30 year Ford diesel tech. Good Job on the video. I will say this to customers that are maintaining their trucks correctly that actually get bad fuel, wrong fuel, or put DEF fluid in their fuel tank and end up needing a fuel system. If you have full cover insurance it will pay for it. I probably average 10 insurance fuel system claims a year at my dealer.

[@FlyingWrenches13]

Thank you!! I’m in the same boat. I have about that same amount of them covered under insurance.

I have a 2019 F250 diesel, I had a failure with my truck. Initially I though it was an fuel system failure, but I noticed a large amount of fuel in the valley of the engine. This fuel comes out soon as the key is turned, is this common? And what May be the cause? The fuel filters were also changed approximately 400 before the event.

[@Carlos-hr9kg]

Love how you described everything man! I learned a lot about these 6.7s from you. I recently started working on powerstrokes at new shop I work at as well as duramax. Came from Chrysler/dodge/jeep/ram, so I learned a lot about Cummins as well. I’m fairly new to diesel work and I love working on these things. Keep up the videos man! Knowledge is power.

[@FlyingWrenches13]

Thanks man. I use to work for Chrysler too. I hated every last one of them lol I’ve recently gotten into the Duramax engines as well. Lots of money to be made from head gaskets/injectors on the early 6.6’s.

[@mattphillips1910]

Excellent video. I still own the first truck I ever bought, which was a 1987 F250 6.9 diesel. It has more than a half a million miles on it now. I also still own a 1990 7.3 that I bought brand new. 300K miles on that one. I have a 1997 7.3 PSD with 200K, and a 2016 PSD F450 with 125K. I've got several others as well, but you get the idea. All of these motors have never had any major failures or system failures. All of them pull trailers at their maximum capacity on a weekly basis. The two things I think that contribute to this success are: A) I don't hammer on them, or ever let them get hot. And B) I change ALL of my filters every 5,000 miles. The fuel filter kits on the newer trucks are about $100. I can buy a whole bunch of fuel filter kits for the price of a new high-pressure fuel system. All of these trucks are paid off and all of them earn me money every week. (Not the 87; she's partially retired and just pulls my horse trailer now.) Filters are CHEAP! And they provide a double savings. The first savings is in the lack of a new fuel system cost. The other savings that people can overlook is the lack of down time. Just subscribed to your channel.

very well spoken dude!!! you're making me keep my 2000 7.3 its a dinosaur but amazing. in May of this year the pickup screen failed on me and the 2 filters were completely clogged in the tank. I fix Asian cars professionally. I Live in Austin, drove to Rogers Arkansas to get my parents 1930 Model A on my 16 foot trailer. everything was fine on the trip up until 1.5 miles from my parents house at 595 miles 1 way. I thought my cam position sensor was failing. replaced it even though it had the recall 11 years ago. I filled it up for the trip to Austin. 4.5 hours into the trip it started misfiring, going 35 mph in the middle of Oklahoma on the side of the road with a restored Model A on the trailer.Ran like shit. I shut it off as I was scared on the side of the road. 10 minutes later I started it again and it got me 25 more miles to civilization and diesel and food.filled it up, had lunch, went south through Dallas until Belton and it started failing again, 20 minutes on the side of the road, 45 more minutes to Round rock, side of the road, 20 minutes, 12 more miles on the side of the road, 20 minutes, 11 miles on the side of the road 4 miles from the house, made it in 13 hours. it was the pickup screen in the tank and the 2 small filters in the fuel module getting clogged with the plastic stuff from the disintegrated pickup screen. pull bed, replaced both filters and pickup screen and its brand new truck again!

[@dougcjohn]

Great informative video; filter replacement & lubrication (ArchOil, Hotshot, etc) is key on CP4. The FASS drop-in filter replacement kit provides superior filtering, water separation & collection, plus air removal. The OEM water separator isn’t great… all the failed CP4’s due to water / bad fuel verify. The FASS traps all water and blocks fuel if water filter is full… better than letting it by-pass and reach pump. Ya, you gotta change filter, so carry 1 or 2 sets if you encounter bad fuel. New 2024 SD 6.7 HO, FASS & HS Top Filter Relocation kits as early mods…. After warranty, DCR pump conversion… unless Ford gets pulled into recent GM Court Ruling recognizing the CP4 as bad design for US Market… precedence has been set and forced to replace or cover.

I think it’s up to $12k now. Fuel additives, fuel filters every 10k-12k miles, get diesel from high flow stations. I use HSS EDT AND their LX4 lubricity additive as well. Do those and you’ll have the best chance of your pump lasting the life of the truck. Fuel filter kits are only like $80 for upper and lower, for my 2015 anyways, and you can do it yourself. Imo save your money on the disaster prevention kit and use additives; good fuel, and maintenance maintenance maintenance!!!

[@tony17601]

The CP4 seems to be the one reason I couldn’t go with a power stroke. GM went to denso for 2017 and up. Ram went back to CP3 after 2 years of cp4. Somehow it’s supposed to work better in a Ford than the other 2? It seems to be finicky at best, shouldn’t have to run additives every tank either. I know better than to put gas or Def into the fuel tank, can I be absolutely certain over the quality of diesel fuel every time I fill up? I love the look of the 2020+ superduties and would love the power no doubt. Just don’t want to worry about having a catastrophic fuel system failure.

[@FlyingWrenches13]

I can understand those concerns. Honestly though, the cp4 pump works great as long as your keeping clean fuel running through it. Most of the trucks I see that need fuel systems are usually because of no maintenance or they pump some rusty water from a off road diesel tank in a field somewhere into it. I can’t convince these farmers to quit running the same fuel they pour in their tractors.

[@garlandmeredith2039]

Hi guys I have an injector question. 2020 6.7 ps, I’m using fords forescan to watch cylinder fuel balancing and the units are displayed in mg. They range from around +.375mg to -.62mg at idle. During a cell +.3-4 to -1.2 and that -1.2 being only 1 cylinder. I’ve got 3 showing to be pulling a bit more fuel than the others. The rest of the cylinders seem to stay much closer together. I also put a little extra Amsoil in and the cylinders came even closer together. Running Liqui moly purge through it now to see how she fares. I don’t know large of a difference that is for this system/motor/application. I’ve been chasing a dpf issue that spurred from a p2002 code and consistent 10% fuel in oil on oil test. This is why we test folks. Oil grows fast now, as in I can notate a difference in a 50 mile trip. SCR seems to stay running at idle when closed and open loop filter numbers range 0 to when it regens. Yesterday I smelled raw fuel and I’ve had a light grayish white smoke on startup I noticed. Today did a snap test at end of trip and got a little black poof. It seems to be leaking just enough to not set a directly related DTC. It could have been doing this longer just didn’t notice as I’ve cared for this truck religiously and didn’t forsee issues at 50k haha. No coolant issues. I believe it to be fuel injectors or a cracked dpf at this point. I’ve done manual regens, used Liqui moly flush, all worked well and numbers look fine on forescan as far as dpf related ones. As long as I keep my oil from growing my distance between regens is 500-600 miles and honestly I think it would be higher without the underlying issue. Concerns I have are that I did fuel filter changes outdoors and while I didn’t think it was an issue, I’ve come to learn the tolerances are at a 1 micron in these injectors meaning the average guys setup has no room for error and needs to be extremely clean. Any thoughts on how I can diagnose with just forescan?

I had my FORD Dealer replace my 2014 F350 CP4 with the newer CP4.2 I also had them install the SPE Disaster Prevention Kit. I change my Oil every 5000 miles without fail (Shell Rotella T 4or5). I change bothe fuel filters every 3 oil changes without fail. I had the CP4 replaced just as a precaution (before the S&S came out). I thought about and was advised by an after market dealer to put a FASS system in but then was told by another it wasn’t worth it. Not sure on that one yet. My buddy who SES driven all types of diesels and pulled loads all over the country recommended change oil every 5000 no matter what and use Rotella T. I’ve know how good Rotella T is for years had another buddy who ran it in ALL his motorcycles and said it NEVER failed him. So there ya go. I agree MAINTENANCE IS PARAMOUNT!!!

I get what you're saying about the kits; hopefully I'll never have to find out if they work!

[@FlyingWrenches13]

Yeah I hope you don’t either! Thanks for the input!

How many miles are you at now and what year is it?

As a quick lane tech, i had no clue how insanely important it was to replace fuel filters on time. I honestly felt kinda shitty for charging so much labor so often but now i see its totally wotth it 😂

[@chriswhittaker675]

Great video sir! Subscribed! Keep up the great work!

[@Olly1775]

Great video sir, you explained all of that very well!

[@americanpride5111]

would you recomend changing the high preasure pump lets say every 100k miles before it has a chance to go out and peace of mind?i change my filters every oil change but this has been on my mind with all the horror stories and my 2019 250 hitting 90k now

[@mikemote1368]

you might take a look at S&S Diesels newest prevention kit. Filters the return line. If pump should go out, nothing goes past the filter.

[@FlyingWrenches13]

Thanks for the info! I’ll check their kit out!

[@adammiller8415]

Not worth it. Replaced multiple systems with this kit that still failed. The only kit with a shot in hell of working is an SPE kit because it has a filter in the kit. Have a truck coming in wednesday with a suspected fuel system failure and he said it has an SPE kit so going to be interesting what its like

[@mikemote1368]

@@adammiller8415 the new Gen2 comes with what looks to me to be better than SPE's return filter. It is an actual element and not just a screen.

[@gianmariavolonte4315]

I see way too many of these 6.7s at our Ford dealership with the problems you just described. Diesels are very popular in our area with the young Country/Amish kids. They definitely are very knowledgeable about tuners and suspension upgrades, but are clueless with maintenance. The 6.7 in it's current generation is a very stout motor, but is unforgiving without timely maintenance. These kids damn near break down when we tell them that it's going to cost $8-9K to fix their mess and their warranty is voided because of all the tuner crap they put on it. All of the older, more experienced diesel owners that religiously service their bone stock engines, 150-200K with minimal issues.

[@FlyingWrenches13]

Couldn’t agree more. It really sucks that the 6.7’s kinda get a bad wrap because of the fuel systems when the real issue is people that don’t do maintenance.

[@tomharvey2824]

Great information. Good video. New subscriber. The people who say that upgrade kit is fantastic is because they get one free for doing the review. I agree with you, prevenative maintenance is key.

[@budk7496]

I have A 2015 f350 6.7 and just went through all my dealer service records ( have our vehicles serviced religiously ) and found the only fuel filter change was at 44k. Is that too long for a filter. Love your Videos.

[@steveperez3393]

Ok, my truck just broke down. Low power mode 1st then stall. Had it towed into the dealer after waiting in 10* weather for 3 hours. I finally get a call that they have found metal in my fuel system. They did not tell me that they have seen this on their trucks before. (Mine is a 2021 F350 SD, 33,000 miles) I’m afraid they are going to try to tell me I did something wrong in the first place. The only thing that happened was my last service approx 1,400 miles back my dealer filled my DEF fluid, which I never told them to do because I didn’t want a DEF mistake to occur. I always, always fill with blue DEF in a box so a mistake cannot occur, but I don’t know if that was the issue or not. I paid sooo much for this truck and no one told me about this problem they were having - now this has happened. I can not be without my truck and now I am totally stuck. Any advice? Should get the sad news today about what they have found.

[@tripfulcher4332]

I get everyone has there own opinion on everything but I'm a firm believer in a disaster kit from s&s bc after getting bad fuel from a local gas station(also I change my fuel filters with my oil every 5k miles) I had my cp4 go out with a kit on and all I did was roll a new pump in and all was well and that's been 8k miles ago.

[@boydhoward8624]

Mason I got a ‘15 that I just put a new fuel system on dropped the tank and cleaned it as well. Now the truck is showing low pressure on the high side yet cranks on starting fluid. You think it’s the rail sensor?

[@jaliscorojo1]

You are the Man thanks for sharing really good video .

[@PhilipRegets]

So I follow your advice on my maintenance regular oil changes 8k and fuel filters every 16k miles and I am still in this situation 160k miles on a 17. truck runs fine but I experienced 2 shutdowns while pulling a trailer ( all oil and filters at a dealership fyi ) their diag says metal in fuel should I get a second opinion

[@joshblack8392]

So with a disaster prevention kit, you should be able to just change pump,filters and be good right? I think my pump is going out but I have the DPK on it

[@jhonatansosa]

have issues with 2017 that will not make pressure to fire up only goes to about 1,300 psi but will start with starter fluid but after that truck will run good. till you let it sit for about 3 hrs then it will not make [ressure again we did the pump because it had black stuff built up on the sensor. would I need the complete system too?

[@andregroulx1439]

well idk when this was made but the sinister diesel gen2 cp4 bypass and filter you should look at the system.

[@FlyingWrenches13]

I’ve seen those before. Just not really sold that they are actually helpful when the majority of the reason these pumps have issues is bad fuel which is also bad on injectors.

[@andregroulx1439]

When this s&s gen 2.1 completely isolates the fuel how can you say it doesn't work? Especially on the low side of the pump????

[@geralddunbar8690]

I have 2017 ford f350 i had put def in fuel the truck stop running the ford dealership said i need to replace fuel system i got the truck towed to another shop the mechanic replaced the regulator the truck runs for 1month and while im towing the truck kills indicating low fuel pressure and reduced it cranks up and i run for a week and the same thing happen this has been a repeating cycle for the last month the truck runs good until its under a load. Do you recommend changing the fuel system or should i start with just replacing the fuel pumps and lines? The truck is currently running

[@RobertoCastro-lu7vh]

So why did they replace the engine? Because of them poring in def in the diesel fuel tank or because of the job not being done right the first time with all the metal shavings in the fuel line system can that cause damage to the engine or does it stop at the fuel injection system

[@scooterinvegas1]

The s&s kit sends the bottom end fuel from the pump (under low pressure) directly through a 6 micron spin on filter on the return side. The top end of the pump only gets fuel from the top of engine OEM filter. Has to be better than nothing imo. At a min, it should save replacing the rails/injectors, maybe.

[@isaacyow4325]

Pulled the fuel control valve on one today truck is showing low pressure on the high side I literally only had 3 pieces of metal in the cavity where the fuel control valve goes truck is obviously a no start with no high pressure I’m suspecting fuel system failure do you think those 3 pieces are enough to Condemn the system

Every how many miles should I change my fuel filters?

[@raymondmcdonald7085]

Good video, commentary and explanation as well as a confident opinion. I recently purchased a 2012 duramax and have been hearing all the CP4 horror stories. I have an extensive background in heavy equipment repair. Not light duty diesels. Any time I see anyone jacking with their rigs putting all these heavy mods on them I cringe. Their are many good mechanics out there who understand these systems but the yayhoos throwing all of the speculation mods on their rigs are asking for trouble. I just never understand how someone doesn't get the correlation of proper maintenance equaling longevity and a more trouble free experience. Okay, off my soapbox. Anyway, keep up the good work!

hey sir! good videos! i am not an expert in powerstroke diesel truck work but i fix, i now have a 2017 ford f350 6.7, the high pressure pump broke, it cracked, i installed a new one, i installed a new fuel pump, the filters, i inspected everything and the system is not contaminated, the truck does not want to start, it only gives me the p2291 code, would you recommend any procedure?

I have a 2021 f350 lariat just hit 144500 miles and got a light on that said low fuel pressure then said reduced engine power, I changed fuel filters noticed small metal particles in the lower fuel filters but changing them fixed the problem, should I just drive it until it goes out or have this down now
