Here's how I dealt with the CP4 in my Duramax..... I sold it and got a truck with the 6.6L gas engine. Fixed.
You need a disaster prevention kit! It reroutes the fuel so if the pump goes out it doesnt send metal through the whole fuel system. Several different kits out there
S and S diesel makes a kit that relocates lines to a separate filter to save the fuel system and motor. It 400 bucks. Might should add it
Ive been looking at stuff like that
Can’t imagine why something like that wouldn’t be a standard if this is a known issue.
@@alanpayne4841because it self admits a large, large, expensive problem that consumers are class actioning about
What’s the link for that product?
@jeremywest9836
I’m sure it’s been said a bunch but fuel treatment like hotshots EDT every fill up plus drain the water separator keep up on fuel filter maintenance install a Disaster prevention kit from S&S or install a cp4 delete from S&S and eliminate it by installing new DCR pump which honestly ford should be doing for us
WOW THAT'S ALL I CAN SAY!. Well other than I'm sorry that it happened to you and other unfortunate souls dealing with the same.. You'll overcome this situation but DAMN AM I SORRY. Hate seeing such things like this happen to good people. And seriously I'm a firm believer in that "They just don't build them like they used to". I swear They/The car manufacturers dream up cheap designs or materials to fail just to stay in business or make more money like paying for the thing at the dealership ain't good enough. Anyways thanks for keeping us updated and sorry again that it happened. Hang tough and don't get too mad about because you aren't alone. See you on the next one good sir and thank you so much as always for bringing us along for the ride. 🙏🙏🍻
In the uk it is usually that the follower turns 90 degrees to the cam so it just wears away the cam and roller, we see a lot but as it’s on the low pressure side of the system if caught early it doesn’t take out the injectors but the whole low pressure side needs to be cleaned
What's funny he stated there was no preventing this but I'm a GM tech and what works to save and prevent the issue with the CP4s on the LML is a Fleece powerflo lift pump that takes the place of the weak factory dribbler in the tank and uses all GM connectors and you can have the choice of upgrading to bigger lines and another thing you can do a return with all of that setup to do basically what Ford calls "the disaster prevention kit".......Also I find it hard to believe that nobody has done for the 6.7 that they made for the LML Duramax and went ahead and designed a CP3 kit to install in place of that junk CP4...... I know for a fact that these 2 items are Legit and are ALIVE AND WELL lol.....I could've swore that the same place that sells the CP3 kit to install in place of the CP4 for Duramax had a kit for the 6.7?? I'd have to double check that for certain though. Well I'm sorry to hear that your CP4 pump murdered your fuel system and that the 6.7 is going to require a major resurrection!! Well if you want me to check that CP3 retrofit kit where I get the GM items just shoot me a message back and we'll exchange info to communicate. Otherwise good luck my friend and again I'm deeply sorry. Update......looks like Fords nobody is making the pump conversion kit like the LML Duramax which is shit if you atleast wanted to go that route to the tried and true Mr. Reliable CP3 to fill that hole and ditch the CP4 all together. For some reason it looks like that company is making a add on CP3 pump kit for the 6.7 Powerstroked which in turn will do what that Fleece pump does for the 6.6 Duramax and add the pressure out of the hole all together to help the CP4......myself I like to do away with the CP4 all together to eliminate any possibility of the problem occurring again and taking a chance of wiping out the damn fuel system. Personally I think its Bosch way of selling parts fue to the sole fact that after Ford went to the 6.7 and GM went to the LML and beyond they arent eating injectors like previous 6.6 models of duramax and the 6.0 and 6.4 BUT.......You hear the fine engineer gentleman over at Bosch tell it and it's as usual....they dumb stupid Americans fault hahaha....what Bosch blames is our quality of fuel and "STYLE" of fuel stating the sulfur content is what's causing the pumps to take a hahaha........one serious question to Bosch and I rest my case....Bosch, how comes neither of the "big 3" here in the states had any major issues and high failure rates of the CP3??? Fuel was still shit then so you say, Thank you kind sir I rest my case and goodnight!!
As I understand, Bosch never designed the CP4 pump to handle North American diesel fuel, and automotive engineers who selected the CP4 knew that. They gambled that failures would be infrequent and the aftermath of failures would be highly profitable for the dealerships. A friend's truck suffered a catastrophic failure and the dealer pulled the old "Never seen that before" with a straight face.
Lol, Ford sells a kit
Man hate it about the truck! But loved the comment “it’s not stripper glitter ✨ “ 😂😂
I love 6.7 powerstrokes, but ima stick with my dinosaur diesel(03 7.3)for now lol. Good luck getting yours back on the road sir!
01 7.3 f550, you need to use your hand to crack windows no AC🤟🏻 will keep it 10 more years,
This is good to know, cause I'm in the market for a Diesel puller..
Get a cummins
Good luck getting her back on the road! Love all the content!
This is what happens when you buy the cheapest diesel you can find at your local git-and-go. Always buy diesel from a high volume seller like a truck stop.. Loves, TA, Pilot/ Flying J. Ez Mart is a no no. High mixes of bio diesel is a no no. Any amount of water will destroy your pump, and always use 1 Oz. of hotshot secret in every fill up. Or not. It's your money. Just my suggestion. Been driving diesels for 20+ years, like to think I've learned a thing or 2.
I only go to big name places, and I am RELIGIOUS with maintenance, using OE parts. Has zero to do with going to a "git-n-go"
One way to fix it for good is a Cp3 conversion. Cp4’s are known to be dog shit no matter what platform it’s on. That’s why all the duramax guys do cp3 conversions and never worry about it again.
The only way to really fix this problem is to sell the truck and buy a gas version. All HPFP are fragile and could go with a bad fillup. I'm sure you'd rather play roulette in vegas and not on a long family vacation while hauling the camper.
I've heard its caused by air forming in the pump when it can't meet fueling needs.
Cp3 won't fit in the valley of a Ford
That's 15k here in /Ca. The prevention kit will save around 12k if not more with pump failure.
So I got 265k out of my truck before this happened. I knew zero about this issue before it happened. Had I known, I would have taken a pre-emptive strike and replaced it before to avoid the expensive decontamination kit cost. But, at 265k, I ended up with new injectors, rails, lines, turbo, and a dcr pump. Runs great again!
I've heard guys replacing with CP3s but those were on early 2000 to mid 2000 models. This is really the only thing that scares me about getting a diesel pickup.
OH MAN! Such a beautiful truck too.😳
Greg aberalla has a recent video on the s&s kit seems like a good investment.
I will check it out
Damn homie that sucks! I had a bad feeling that was the culprit. I been driving the beater keeping the miles down on the 6.7 but sitting around hurts them also 🤦♂️
The disaster prevention kit is the at top go. With it all you would need in the event of a failure is the CP4, filters, and flush the tank and frame lines. Much cheaper repair. The kit may be on backorder through Ford right now, but there are places online that stock the OE kit that have them right now.
The potential for a complete and utter disaster like this would make me never ever want a diesel
I have a 2013 super duty with 117,xxx maybe I should look into doing this when I put new front hubs and sway bar end links on
If it were me, I would do it by 150K, save yourself 7K
For my 2/cents. Those are good pumps, but poor fuel quality will take them out. I just installed a s s disaster prevention kit on one of my customers trucks today. I would highly recommend this. It will save a shit load of cash down the line. I have some experience as I've 😢been a Ford tech since 1987. Specialized with diesel since 1989.
This is also why I drive old stuff...its cheap to fix and most of the time anyone that can turn a wrench can fix my stuff..
I stand corrected they offer a kit for the duramax and Cummins and I thought they had 1 for the powerstroke but do not
Its a lubricity problem, crappy fuel and lack of a fuel additive does not help. Use good fuel, fuel additive every fill up, drain your water fuel separator, & change your fuel filters every 10,000 miles. I know you were traveling that makes it hard to find a good fuel station to fill up. Sorry for your loss, hope you get it running soon!
Holy Crimney! That is a ton of money to fix that! WOW! So sorry Brother!
I have heard that the Diesel's are great until something goes wrong, then bend over, because the repairs are astronomical! I have heard for some things it is necessary to pull the whole cab off the chassis to replace parts. Too rich for my blood.
Thanks buddy, we will get it back rolling
Midsouth power I Memphis has all the parts in stock
Damn I got a 2017 F350 with 160+ on the clock guess I'll be spending some money soon.
I would swap it out, spend 1500 or 9000
Don’t crank them dry keep your fuel filters clean and run good diesel
I do, it didn't help
@@FoxcastMedia oh they still suck lol but coming from experience over half of the ones that die are from people changing fuel filters and not priming correctly and hurting the pump
I wondered where Jefferson’s Z28 went to from Fast Times at Ridgemont High….
Most people here put a cp3 on they have a better life expectancy.Run some additive in you tank to keep the pump lubricated.
I have been looking all kinds of options
From what i understand diesel has low lubricity with low sulfur. I add stuff to my furnace so the pump doesnt get cranky. I use Howes which is what every trucker i have met uses. My son works in Alberta as heavy equipment operator and every place he works uses diesel conditioner in their equipment and he borrows some for his truck :) His is duramax ,just put a cp3 with a tune.
these pumps are avail REFURB on e-bay under $800, I have 270K on my 2014 F350 6.7 still the same pump
Oh brother that stinks for sure! One of those deals, got to get it fixed & on road 👊🏻
When the fuel truck pulls up to the station and inadvertently puts gas in diesel tank, welcome to diesel pump problems.
First thing I would do when I got it back take it right down to the Ford dealership trade it on the coyote truck and ad d a turbo later..
Exactly !!! Kind of a no brainer. Lol
Come on now we'll be waiting !
Hmmmmmmm
I thought cp4 was only on ford's, but looks like duramax and Cummings are also victims. Thanks for the video.
Add lubrication to your fuel
That’s kind of the same deal with a Cummins ISX 2350 the pistons in the fuel pump they were made of ceramic those started getting ate up by the cam and contaminates the whole fuel system …… talk about big bucks to fix , Big trucks big bucks 😖
Yup, part of it I guess
Stripper glitter, LOL 😂. Hopefully it doesn't hit that wallet too hard.
It hit hard lol
mine has a C3PO
I heard put half quart of transmission fluid in the tank every once in a while should help lubricate
I have as well
You can convert it to CP3. Ive seen kits online
please define the causal mechanism for poor diesel fuel lubricity?
After the Duramax CP4 failures 2011 to 2016 LML engines why would anyone even consider buying a truck that has a CP4. Ford continues to use them and they blame the failures on bad fuel and will not cover it under warranty. CP4 pumps have a mechanical design flaw problem that allows the roller cam follower piston to rotate and start digging metal. Anyone that buys a truck with this pump you should expect this to happen. Ford could care less and will never have my business. How an owner can be okay with this and consider replacing the $3500 pump at 100,000 miles as preventive maintenance is beyond me? IQ test?
All the pumps in 6.7's are CP 4.2's. 2 cylinders. Convert it to a DCR pump.
2 cycle oil
Actually one thing that can be done is fuel additive, we sell FPPF products, it's the best on the market, the best is
total power, it has fuel power for water, cetane improver, lubricity, injector cleaner, should used at every tank fill
up, is a preventive measure and will extend the life of the fuel system. I work on all types of diesel fuel systems,
rebuild most, the problems that i see is water damage, see the EPA many years ago wanted to remove the sulfer
for #2 diesel fuel, which makes the fuel drier, a lot less lubrication, and the process actually add water to fuel,
doesn't matter if you can your fuel filters all the time, the water is too small to be caught by the filters. And the
Bosch CP4 is a crap pump, Bosch has a ton of more of the CP4 failures compared to CP3 , the design of the
CP4 is more the problem than anything.
Diesel just seem like a hastle with exhaust fluid and all that stuff
The aisle is worth it most of the time lol
They use return fuel(dirty fuel)to lubricate the pump. There’s a company that makes a plate that redirects the fuel an lubricates the pump with clean fuel an it really prolongs the life of these pumps
What fuel pump is in my Jan/08. 6.4 Super Duty? It's Jan 2024/ and I got 140K miles on her deleted and running a 4" catch can with 1" ID tubing in and out seem to work fine. Miny Max set at stock to tow-hall low boost fuel set at two never been raced. What's your best guess put in return line filters and replace the high-pressure fuel pump. I'm guessing that is your best option 😢
I’ve a S&S Bypassed 2011 F250 6.7 with 214,000 miles. Again, It is bypassed, I run certain religiously and give it everything it needs when it needs it. My question is, can I, overhaul my CP4 anticipating that it is getting to the end of its lifespan? I’d rather do that than have it go bad at a remote spot in the backcountry. Someone “knowledgeable” please advise.
How many miles was on it when this happened?
What all did you do to your truck while you had it apart?
That OBS chevy though!!
Please tell me the running board you have. I need to replace mine. I have a 2013
Well, if you did change your fuel filter every 10k miles, that didn't work out so good. Just bought a 2022, now second guessing that. Looking at an aftermarket fuel pump. But, the warranty goes away. But just like you, I don't want to end up alongside the read with my big ass 5th wheel. Argh
I watched all the commercials for you... at least you know it's good for awhile now.
This why these new trucks sucks 2006 in down is better.
The old 6.0 had plenty of issues too. Part of the game I guess.
@@FoxcastMedia nah 2005 in 7.3 and 6.0 with banks turbo upgrade was the best these new 6.3s with all this emissions is garbage problems they just look good and way over priced.
Disaster prevention kit, $400 and that will keep the damage to just replacing the pump.
Sucks, hope you get it figured all the way out
What is the normal cost to change the pump before it fails?
I believe around $1500 or so
How many miles before yours went out? I have a 2017 6.7
After this you should name the truck Steve Austin/Lee Majors. After all, “we can rebuild him; we have the technology “. And I know you’ll bring the truck back bigger, better & stronger than it was before.
Dang man that really sucks !!!!! I honestly have never cared for anything diesel looking at what everyone spends keeping them on the road it might be time to open a shop just for diesels 😂 😂
If you tow or farm or pull a heavy camper....you need a Diesel. But...7 out of 10 buyers never haul or tow anything...you know ...the "Roll Coal " Bro's. Those guys must just like the $400 oil and fuel filter changes for the hell of it. Why complain about the high high high cost of repair and just plain ownership....YOU BOUGHT A DIESEL...sorry about that I guess.
So you are saying every 100,000 miles to 150,000 miles replace the fuel pimp?
Just had my 2nd CP4 pump failure in 10k miles. 😡😡😡😡
Sounds like you didn't get all the metal out the first go around.
Tried and true cp3 do it once and be done they’re nearly bulletproof and w bolt on mods it’s def gonna hold Up just get a single cp3 kit
Or get the cp4, a lift pump, and a exergy fuel saver filter kit for the fuel pump itself!
You can’t cp3 swap a 6.7 powerstroke. The pump doesn’t fit in the engine valley
Disaster prevention kit
F o r d fix or repair daily
Air dog fuel pump
My 2017 with 88k miles is at Ford right now for $15k in repairs... Its bullshit !!! The pump is the ONLY PART NOT COVERED UNDER THE 100k WARRANTY....BULLSHIT !!!!
I love Ford but if you got to have a diesel make it a Dodge
Doesn't the Cummins use this same CP4 pump? Or at least some of them? Same with Duramax? Point is, this isn't just a Ford problem, unless I'm missing something.
Dodge runs the same pump
@@piptyson5512 not anymore 19 an 20 ran cp4 the 21s an newer went back cp3
That is not totally true you scrape that crappy ass cp4 pump and do the cp3 kit on it and no worries
Sell that junk and get a Godzilla
No thanks, diesel is the king for pulling
Don't buy a ford truck..2020 2021...they have recalls..and so many 2021 haven't even been finished getting built.f250 f350 have bad rearend..Google it.youtube it..you will see..and the fix is a half ass job..
Get a fuel pump
F o r d ...find on road ded
Sell that heap and buy a chevrolet i own fords but aways use my chevy for pulling.
Lol Duramax uses the same pump
