Was about to say this too😂doesn't matter if it's a Chevy ford or diesel I'm sure any truck or car could run endlessly if the maintenance is top tier or just good enough.
Additives can make a huge difference. I ran additives in my diesel and made the engine run way nicer. The off boost - boost transition was much improved. Just saying the right additives can make a great difference.
I think the #1 killer of the CP4 is fuel temps. The fuel tank is also the cooler. When operators run their tank(s) low, and since these are all "return" systems, the hot fuel is unable to maintain film strength. With the extra fuel he carried on this truck it's unlikely the tank was ever ran down to this critical level where the CP4 suffered insufficient lubrication. Wish more operators were like this man and took great care of their equipment. Kudos to him for proving it can be done!
I work in diesel injection. That man knows the secret. Prevention is key. Running your machine is key. These CP4's and even CP3's are tough, simple pumps.
Strong & simple they are but it only takes a little dirty\wet fuel to grenade one causing the dreaded contaminated fuel system replacement at $10k+. The Stanadyne DCR pump is so much safer and more durable for a $2k pricetag it's the best [fuel system]insurance you can buy for 6.7's!
@tdotw77 that's the bane of a common rail system. I often get injectors wrapped in dirty rags to test out. Pumps without caps full of dirt and grime. I tell my clients that a single grain of sand can ruin an injector and then cause all sorts of problems.
@@fink94 I don't think people realize how super sensitive they are to any kind of dirt or contamination. That's why there's 2 filters and several screens inline on the supply system, it's not like your old mechanical tractor that wasn't as hyper sensitive. 👍🏻
@tdotw77 for sure. I do Rossa Master, DB's and DPA pumps for old tractors and whatnot. These pumps would run with gravel in them! Some are from the early 60's and they're easily rebuilt to this day (the hydraulic head does wear out though)
I'm in europe, and the fact that we don't have anywhere near the problems you have in the US with these pumps, makes me pretty confident you have something going on with your fuel. And the fact that this guy didn't have problems could be explained by the fact that he never let the car sit, because if you have water in the fuel (TINY droplets) letting it sit would allow it to make micro pitting in the pump cam and roller causing it to fail rather quickly, but driving it daily would prevent the pitting from ever occurring. The main difference from the CP1 pumps that doesn't seem to have this issue, is that there is a teflon lining on the rotor that rides the cam, this would handle pitting more gracefully as it isn't metal on metal like the CP4.
It’s pretty widely known at this point that american diesel and fuel in general has historically been of poor quality. The cp4 would also occasionslly fail in the tdi engines in the Us, and from what i know, it’s not a common failure for tdi engines in central europe. The problem isn’t Bosch, it’s american truck manufacturers using a pump that’s not designed for the diesel available in the US. Also, fun fact, fuel quality is also the reason many manufacturers that sell cars in europe are able to recommend ”crazy” oil change intervals of 20.000 miles using low saps oil, while in the Us, those same manufacturers put the roof at 10.000 miles usually.

That was severe duty, to understate things. Changed oil every 5,000 KM which is about every 3,000 miles. Cheap care. It also makes your stress levels drop.

Fuel additives for lubrication is key and filter maintenance… plenty 6.7 CP4 do 300k plus with maintenance. Many don’t even know about the CP4 problem, just working & caring for their diesel. The percentage that actually fail isn’t as high as perceived through all the TH-cams and articles… including the larger 550, 650, etc trucks. In addition to additives & filters, I’d highly agree with a disaster prevention kit, FASS filtration and moving to DCR pump… for my preference… but I meet them often, high mileage and they have no concern or knowledge of a problem. So it’s not out of norm, high percentage fleet maintenance, farmers, oil rig, etc maintain their rigs religiously and easily go beyond 300-400k miles. Oddly I hear more of the 250, 350’s having CP4 failures.
Ya its unreal when u watch you tube you would think every 6.7 is bad we run 6 of them hard with hired hands and only 1 needed a rutrbo under warranty the rest have high miles and have been bulletproof
@@forrestcowan448exactly, your situation is what I often see… hard working diesels and few issues after warranty. Crews may work them hard, but they’re maintained. The Owner in Video mentioned he felt it was daily hard use that “kept” a Diesel happy & healthy, that may have merit.
A lot of problems with diesels started when they removed the sulfur and went to ultra low sulfur diesel years ago, using the fuel additive for lubrication is key to preventing wear of injector pumps and seals.
I seriously believe in early maintenance. I have a 2010 f150 4.6 3v with 522000 km on the clock and I change my oil every 10k, trans case and diffs every 100k and only use ford filters and synthetic oils. Runs like new still
I've been saying for decades, change the diesel oil every 20k bcuz soot kills diesels. Also fuel and filters bcuz fuel is filthy at the pump. Your diesel will last 1 mil miles no problem. You go one better and get an aftermarket lower micron oil filtration system. Then you skip an oil change and just change the filter. Also get a quick release oil plug for the oil pan. Just sayin.
@dsstaang Any diesel will have soot in the oil. I don't need to test the oil. Just take out the dip stick and u see how bad it is. I've had Freightliner, Cummings, Paccar, Chevy, and it's the same story with maintenance. I think the manufacturers don't want a better running engine. Fuel efficient yes but better contaminate mitigation absolutely not. It's like evrythg else with don't make it last, let it crash for quicker turnover and bigger profit. Now they have added the DEF system which is such a joke. All it does is break down and rob power. Why not make a totally efficient engine that lasts 1 mil plus miles. But that would make sense for the buyer no cents for maker. 💩😳
@@justsayin5177 Any diesel will have soot! Cummins has a higher failure rate than any of the other manufacturer's. EMD made diesel engine's to run millions of miles. I maintain one last overhauled in 1974 it is a 1958 model & it's still working. You don't change oil in the bigger Diesel's by looking at a dipstick. You send in oil samples for analysis. Yes! All newer Diesel's with the exhaust filters & or def are designed to fail. No matter how clean your oil or fuel is you still have #6 on a Cummins getting coolant last so if worked hard #6 will eventually fail. It's just a bad design flaw. On top of the fact it's hard to get new Cummins part's. I have had one down 4 months waiting on part's. Cummins rep answer is always the same we are working on it just a few more weeks. 😂 Nobody make's some of the new parts except Cummins. They have the market cornered.
He got away with 15,000 mile oil changes because he was doing highway miles, not city miles. An engine running a constant RPM experiences very little stress and wear.
Yep.. The heat cycles are what really eats at everything.... Plus, I'm not sure how much these hold.. but my 7.3L holds 4 Gallons of oil. 15k is not really that long for that much oil being circulated... Tractor/trailer semi trucks usually go at least 25k miles before changing oil.
That was very interesting on the ford truck with high mileage it just proves that regular maintenance on a vehicle regardless of diesel or gas he do your maintenance and treat your right
Diesel fuel is considered " light oil " thus holds abrasive grit so filters get the workout and need replaced often. Boron nitride in various fuel additives is a good extreme pressure lubricant. Merry Christmas all
I commented on one of your earlier videos that additives like HotShot are essential for the health of ANY diesel engine in the US. They use a higher percentage of sulfur in the fuel in Europe where CP4s were developed. Sulfur is the lubricant in the fuel system. It’s common sense.
They’re not going to tell you, since Dave’s selling his own additive… this is Dave’s first step to hell. Not sure why Dave feels the need to start selling stuff given he’s obviously doing VERY well.
I have a 2019 GM L5P and I got it new with 1 mile on the track. I use Amsoil signature series 5W40 oil and I use Amsoil oil filter. And I use Wix fuel filter because it is a synthetic filter media that filters down to 2 migraines and I change it every 20,000 to 30,000 miles depending on my driving. If I’m pulling a lot I’ll change it around 15,000 to 20,000 miles. And I usually Amsoil all in one fuel additive every 4 tanks of fuel or so, or if I’m driving up in cold weather in the mountains. And I do that because I always use high-quality diesel fuel from Chevron or 76 fuel stations. And I charge my air filter every 30,000 miles.
He is using bypass oil filtration. The insane diesel filter he talks about at the beginning is a bypass. Cat has been using them forever. Amsoil sells them as well, or you can make one yourself for a little over a hundred bucks. It runs the oil through a fuel filter, 1 or 2 micron instead of 20. The best one you can buy is ops-1 eco pur. It removes liquid contaminants, not just solid. It’s a grand.
We have 2 lgh duramax trucks at work with 400k miles on them and still have the original cp4 pumps in both of them with no issues oil and filter and fuel filter changed every 5000 miles no blow by on either engine they have been pretty good trucks
15,000 mile oil and filter change intervals is NOT preventative maintenance ESPECIALLY when towing the whole time and ESPECIALLY with a diesel engine! Guy always used quality fuel and always added extra lubricity and that's what got him to almost 900k miles imho!
Its not just mileage. Hours are the most accurate meter on engines as far as how often oil changes are needed. This truck due to hotshot work can put on 15000 miles with similar hours as the average truck at 75000 miles due to all highway driving.
we run howes and plenty of it every fill up in our 6.7s and weve never had issues pushing over 160k in both and change fuel filters with oil changes. the older equipment always said buy clean fuel keep it clean. remember when you try to save money you spend money
my jetta 2.0T i consistantly have done 10k oil changes since i bought it with 5k miles now it has 184k on it been upgraded turbo from 200 hp stock to 350hp since 40k miles and been run hard she still running strong
We have 300 6.7 fords and the only CP4s we’ve lost are the ones that got DEF or gasoline in the fuel. We do Ford MotorCraft fuel filters every 10,000 miles. CP4s only fail when they get contaminated fuel. I think in the last 5 years we’ve only replaced 3 CP4s.
The cp4 pump additives have obviously helped it live But the pump is a lot older than newer versions could the metal that has been used in the pump be better quality steel than the later models As manufacturers look to save money on materials to keep costs low maybe you could get a metal urologist to compare the older pump to newer versions and get a better insight to the quality of the older models
I use marvel mystery oil and power services additives helps lubricant everything Every 3 rd tank ... this has worked on all our equipment trucks farm equipment And 4 trucks with original engines 300k no injection pump issues 👍😎
I don't think it's necessary.. I have over 300k miles on my 2002 7.3L.. and I've poured in old used motor oil.. and poured in ATF.. It doesn't matter. Your truck will run on bacon grease or vegetable oil. It does not care.
I replaced a cp4 on a 2013 LML with 730,000 km it was still going strong but I was doing the head gaskets so figured I might just aswell do the pump and injectors. I I use stanadyne fuel additive in all my duramax's (2007-2024) never had a pump fail
That's better than me. I lost the wrist pin on number one on my 06 lbz. So I lost the head and the block. I took the head bolts out with my fingers. There was no torque on them. I guess that I should have gotten the motor rebuilt in LA and not driven home to Salt Lake City. The block cracked in Saint George. Lost all the coolant and still drove six hours home. I had 500,000 and only replaced glow plugs and changed oil and filters.
I’ve got an 08 Silverado 3500 HD LMM Duramax 961,000 miles original injectors still in the truck original CP three in the truck I service every 10K 9 quarts of shell Rotella 1 quart of Lucas and always a must AC Delco filters, air fuel oil every oil change a must
I used to add castrol 2-stroke oil (for water cooled engines) to my fuel in my 04 duramax. Don't know if it helped as I sold the truck years ago, but it certainly didn't hurt.
So here’s the takeaway which pretty much every good 6.7 owner knows. Buy fuel at truck stops or close to the interstate as much as possible. Keep it treated.. period. I don’t care how or what flavor. Change the oil sometimes rarely
As a mechanic who work's on them daily. That's really hard to believe. We don't even run Cummins service truck's to work on & run around servicing them. Really hard to get newer Cummins part's too. I have an engine down now waiting on part's ordered 4 months ago.
What fuel additive did he run I have a 2024 6.7 ho and am sacred to death of this happening I am running Hotshot secret edt in every tank and probably dose it a little heavy hoping to put this problem off until I can afford a dcr conversion great video have a great day thanks.
I have an 06 dodge , with a Cummins. It sits 99% of the time . Never go over 3000 miles per oil change . Keep in mind I only drive it that many miles per year .
And they say unicorns don't exist! I'm an extreme skeptic who believes almost nothing that most customers say, but if that's actually an OE pump at that mileage, it deserves a billion dollar research grant into why it didn't fail before a quarter that mileage.
Can we get an aftermarket parts list from this guy? Oil bypass system, im assuming? What fuel filters was he running? Factory or not? Any add ons to that? We need to know more....
Gd day from Ontario I wonder how many hrs that was. We have neighbours who use diesels for generators They put 60,000 hrs on, put running 12-14 hrs /day every day other than Sunday Ths
It's a miracle. Someone who took care of their vehicle.
Was about to say this too😂doesn't matter if it's a Chevy ford or diesel I'm sure any truck or car could run endlessly if the maintenance is top tier or just good enough.

If you sample your oil it let's you know. I do alot of oil changes because of excessive soot.
It's normally a Cummins engine.
@dsstaang
Any diesel will have soot in the oil. I don't need to test the oil. Just take out the dip stick and u see how bad it is. I've had Freightliner, Cummings, Paccar, Chevy, and it's the same story with maintenance. I think the manufacturers don't want a better running engine. Fuel efficient yes but better contaminate mitigation absolutely not. It's like evrythg else with don't make it last, let it crash for quicker turnover and bigger profit.
Now they have added the DEF system which is such a joke. All it does is break down and rob power. Why not make a totally efficient engine that lasts 1 mil plus miles. But that would make sense for the buyer no cents for maker. 💩😳
Is what i do to my cummins, but i idle a lot, so we'll see.
@@justsayin5177 Any diesel will have soot! Cummins has a higher failure rate than any of the other manufacturer's.
EMD made diesel engine's to run millions of miles.
I maintain one last overhauled in 1974 it is a 1958 model & it's still working.
You don't change oil in the bigger Diesel's by looking at a dipstick.
You send in oil samples for analysis.
Yes! All newer Diesel's with the exhaust filters & or def are designed to fail.
No matter how clean your oil or fuel is you still have #6 on a Cummins getting coolant last so if worked hard #6 will eventually fail.
It's just a bad design flaw.
On top of the fact it's hard to get new Cummins part's.
I have had one down 4 months waiting on part's.
Cummins rep answer is always the same we are working on it just a few more weeks. 😂
Nobody make's some of the new parts except Cummins. They have the market cornered.
Maintenance goes a far way. I've got 1.4 million miles on my 2016 Cascadia DD15.. oil & filters changed every 10,000 miles.
Every week oil change?
@repairvehicle Truck does 2 trips a month to the east coast n back, so once a month oil change.
@@Stavros1977 engine has zero repairs? Original injectors and turbo?
@@repairvehicle Just lots of maintenance and Lucas fuel additives.
@@Stavros1977how many times did you replace injectors and turbo?
He got away with 15,000 mile oil changes because he was doing highway miles, not city miles. An engine running a constant RPM experiences very little stress and wear.
Yep.. The heat cycles are what really eats at everything.... Plus, I'm not sure how much these hold.. but my 7.3L holds 4 Gallons of oil. 15k is not really that long for that much oil being circulated... Tractor/trailer semi trucks usually go at least 25k miles before changing oil.
That is an incredible amount of miles! Please tell us what additive you are using.
That was very interesting on the ford truck with high mileage it just proves that regular maintenance on a vehicle regardless of diesel or gas he do your maintenance and treat your right
Amsoil for sure based on the cost mentioned
I wanted to hear additives and filter and oil brand
@@DuaneWilson-ro1pn what brand of oil and filter will cost $200 per oil change?
We use amsoil in our fleet and never have engine issues.
there fuel cleaner, oil, and trans fluid is in all our vehicles. We also use wix filters
Diesel fuel is considered " light oil " thus holds abrasive grit so filters get the workout and need replaced often. Boron nitride in various fuel additives is a good extreme pressure lubricant. Merry Christmas all
Been a few million mile 6.7 fords. Some with emissions still on it
DAVE, What diesel fuel additive do "YOU" recommend???
His relabeled "sauce"
Dave’s the GOAT! When are you going national? 😊
I run a synthetic two cycle oil to mine once a week not super heavy but it's paid off along with the Extreme diesel additive
Dadgum unicorn right there.
I commented on one of your earlier videos that additives like HotShot are essential for the health of ANY diesel engine in the US. They use a higher percentage of sulfur in the fuel in Europe where CP4s were developed. Sulfur is the lubricant in the fuel system. It’s common sense.
EDT by hot shots has been our go to for decades of 4 diesel service trucks. Clean/ reliable returns
ITS BEEN ASKED SEVERAL TIMES but no one has provided the answer! WHAT diesel fuel additives does he use?
Any alcohol-free additive. Opti-lube is the best backed by testing.
my bet it was ar6500
dave sells his own additive called secret sauce
@@chunukbair9506 He hasn't provided one shred of testing either. He literally copied the design of the bottle from opti-lube.
They’re not going to tell you, since Dave’s selling his own additive… this is Dave’s first step to hell. Not sure why Dave feels the need to start selling stuff given he’s obviously doing VERY well.
yep a decent fuel conditioner will keep things nice. and of course regular filter changes. have good clean fuel and keep it that way.
No DCR and high idle hrs, love it! Against the grain
I have a 2019 GM L5P and I got it new with 1 mile on the track. I use Amsoil signature series 5W40 oil and I use Amsoil oil filter. And I use Wix fuel filter because it is a synthetic filter media that filters down to 2 migraines and I change it every 20,000 to 30,000 miles depending on my driving. If I’m pulling a lot I’ll change it around 15,000 to 20,000 miles. And I usually Amsoil all in one fuel additive every 4 tanks of fuel or so, or if I’m driving up in cold weather in the mountains. And I do that because I always use high-quality diesel fuel from Chevron or 76 fuel stations. And I charge my air filter every 30,000 miles.
He is using bypass oil filtration. The insane diesel filter he talks about at the beginning is a bypass. Cat has been using them forever. Amsoil sells them as well, or you can make one yourself for a little over a hundred bucks. It runs the oil through a fuel filter, 1 or 2 micron instead of 20. The best one you can buy is ops-1 eco pur. It removes liquid contaminants, not just solid. It’s a grand.
We have 2 lgh duramax trucks at work with 400k miles on them and still have the original cp4 pumps in both of them with no issues oil and filter and fuel filter changed every 5000 miles no blow by on either engine they have been pretty good trucks
Do they get ran low on fuel?
15,000 mile oil and filter change intervals is NOT preventative maintenance ESPECIALLY when towing the whole time and ESPECIALLY with a diesel engine!
Guy always used quality fuel and always added extra lubricity and that's what got him to almost 900k miles imho!
Its not just mileage. Hours are the most accurate meter on engines as far as how often oil changes are needed. This truck due to hotshot work can put on 15000 miles with similar hours as the average truck at 75000 miles due to all highway driving.
@kennethobando5755 Going by hours is for engines that idle a lot and being a cross country vehicle going by mileage is best.
we run howes and plenty of it every fill up in our 6.7s and weve never had issues pushing over 160k in both and change fuel filters with oil changes. the older equipment always said buy clean fuel keep it clean. remember when you try to save money you spend money
my jetta 2.0T i consistantly have done 10k oil changes since i bought it with 5k miles now it has 184k on it been upgraded turbo from 200 hp stock to 350hp since 40k miles and been run hard she still running strong
That is freaking amazing!!
I’m glad your showing people how to avoid coming in for engine replacenent
Extended oil changes are absolutely fine! As long as you’re replacing the filter with an extended interval filter.
We have 300 6.7 fords and the only CP4s we’ve lost are the ones that got DEF or gasoline in the fuel. We do Ford MotorCraft fuel filters every 10,000 miles. CP4s only fail when they get contaminated fuel. I think in the last 5 years we’ve only replaced 3 CP4s.
What oil and additive was this gentleman using?
Hotshot is the best additive
Its what i use on the Sprinter van and its kept it running well
EDT has kept my truck purring. Even the lift pump is beyond the normal usage term. Lubricity
The cp4 pump additives have obviously helped it live
But the pump is a lot older than newer versions could the metal that has been used in the pump be better quality steel than the later models
As manufacturers look to save money on materials to keep costs low maybe you could get a metal urologist to compare the older pump to newer versions and get a better insight to the quality of the older models
I use marvel mystery oil and power services additives helps lubricant everything
Every 3 rd tank ... this has worked on all our equipment trucks farm equipment
And 4 trucks with original engines 300k no injection pump issues 👍😎
I don't think it's necessary.. I have over 300k miles on my 2002 7.3L.. and I've poured in old used motor oil.. and poured in ATF.. It doesn't matter. Your truck will run on bacon grease or vegetable oil. It does not care.
It’s a ford that’s why
“We see pumps go out at 40,000 miles”
@@AquaticLogiclots of variables to a CP4 failure
Ford doesn’t even make these pumps there smart guy
The old dental saying- only floss the ones you want to keep
Only maintain the engine you want to keep
You guys are awsome
What fuel additive did he use?
"You can pay me now, or you can pay me later" commercials ringing in my head.
What additive did he use? Someone from Dave’s shop
I replaced a cp4 on a 2013 LML with 730,000 km it was still going strong but I was doing the head gaskets so figured I might just aswell do the pump and injectors. I I use stanadyne fuel additive in all my duramax's (2007-2024) never had a pump fail
Heheh you were doing heads lol ……….. sorry
😂 Edited
That's better than me. I lost the wrist pin on number one on my 06 lbz. So I lost the head and the block. I took the head bolts out with my fingers. There was no torque on them. I guess that I should have gotten the motor rebuilt in LA and not driven home to Salt Lake City. The block cracked in Saint George. Lost all the coolant and still drove six hours home. I had 500,000 and only replaced glow plugs and changed oil and filters.
Love this
I’ve got an 08 Silverado 3500 HD LMM Duramax 961,000 miles original injectors still in the truck original CP three in the truck I service every 10K 9 quarts of shell Rotella 1 quart of Lucas and always a must AC Delco filters, air fuel oil every oil change a must
I used to add castrol 2-stroke oil (for water cooled engines) to my fuel in my 04 duramax. Don't know if it helped as I sold the truck years ago, but it certainly didn't hurt.
Today, that might hurt. Everything in modern diesel needs to produce little to no ash
Love my 6.7
This is exactly why I said before Dave’s lied when they said it’s a matter of when and not if they fail.
It’s simple, do regular maintenance!
What fuel additive is he using? I wonder if they are not saying because they sell their own now.
Oh for sure that was my thought exactly! I figured it’s archoil or HSS EDT but it want Dave’s secret sauce so no mention
The very first part on pump removed looks like new/er blue gasket material @ 1:50.🤷♂️
Ok, can we get the oil and additives dude using i got a very strong feeling dude using amsoil or something close to the same quality
I use AT fluid in my fuel for lubing the fuel pump. It is a CP4 with 105k and no problems
Dave, I have a GMC with the 3.0L Duramax. Do those engines have problematic issues with the fuel pump like the CP4 pump?
So here’s the takeaway which pretty much every good 6.7 owner knows.
Buy fuel at truck stops or close to the interstate as much as possible.
Keep it treated.. period. I don’t care how or what flavor.
Change the oil sometimes rarely
What was the additive he used ??
Unreal😮😮😮
Was the truck deleted?
Probably 🧐
Dude, I watch you because of the old-school teaching, not because of the give aways or trying to sell me stuff!
Know a lady who has 2 cummins with million miles. Every other oil change does trans service and fuel filter no issues
As a mechanic who work's on them daily.
That's really hard to believe.
We don't even run Cummins service truck's to work on & run around servicing them.
Really hard to get newer Cummins part's too. I have an engine down now waiting on part's ordered 4 months ago.
This is not unheard of. He used an additive (probably HOTSHOTS) BUT 900,000 MILES on a diesel truck is not unheard of
stopping on the throttle will shorten the live on these be nice and rolling in so much better
I'm curious about his dpf/ecr systems in 900k miles.
Your catching alot of flies in that thumbnail 😂
What year was the truck?
What fuel additive did he run I have a 2024 6.7 ho and am sacred to death of this happening I am running Hotshot secret edt in every tank and probably dose it a little heavy hoping to put this problem off until I can afford a dcr conversion great video have a great day thanks.
What year and what additive
On my 2017 Duramax I use Stanadyne, Howes,Liquid molly 7180
My Trucks Runs like a Champ .133,000 thousand.
What did you use sir?!?!?!?!? 2014 6.7 powerstroke and would love to know what additives you use
The cp4 is like a 6.0 powerstroke. Do the right things and it’ll last. Or just run it and it’ll blow and cost you.
I have an 06 dodge , with a Cummins. It sits 99% of the time . Never go over 3000 miles per oil change . Keep in mind I only drive it that many miles per year .
Any word on what additive was used? Let us know Dave, I think it's important info since so many additives are snake oil.
How long before the Denso Hp-5 pumps start coming in from the Duramax 3.0L
What is the additive?
And they say unicorns don't exist!
I'm an extreme skeptic who believes almost nothing that most customers say, but if that's actually an OE pump at that mileage, it deserves a billion dollar research grant into why it didn't fail before a quarter that mileage.
Can we get an aftermarket parts list from this guy? Oil bypass system, im assuming? What fuel filters was he running? Factory or not? Any add ons to that? We need to know more....
So what kind and brand of additives was he using?
Gd day from Ontario I wonder how many hrs that was. We have neighbours who use diesels for generators They put 60,000
hrs on, put running 12-14 hrs /day every day other than Sunday
