    I preferred to make the conversion to CP3 to avoid the damage of all injection components. In case of a damaged CP3 you will replace only the pump itself, not the whole injection components, like a junk of CP4. This is the main advantage of CP3.

    2014 gmc 2500hd duramax purchased with 53k, cp4 failed at 56k less than 3,000 miles after purchase. Aftermarket warranty refused claim, was blamed on wix's new plastic filter install by local GM dealership. Left me with a $3,705.00 Southwest warranty that wouldn't cover a cent. GM quoted 16k for fuel system replacement. Performing the work at my employers facility for 4k in parts and 20 hrs labor. Corpus Christy, Texas cp4 lawsuit settlement is very interesting.

    I have a 2019 RAM with Cummins, equipped with the CP4. I have 9,500 miles on the odometer. The truck has been recalled for the CP4 pump, with no fix in sight. Because of your excellent video, and others I have watched, I am now using Diesel Kleen to lubricate the CP4 pump. In my opinion, RAM should be advising their Cummins customers to immediately start using Diesel Kleen, because it is now recommended by Cummins. And, RAM should be sending Diesel Kleen coupons to their customers. Diesel Kleen should be free, until the CP4 is replaced.

    I own a 2019 RAM with Cummins. I live near Toronto Canada. Our winter temps do go below -18'C. Make sure you use 5W-40 synthetic oil. It says so right in the manual. In April 2021, my local RAM Dealer used Shell Rotella 10W-30. I drove my truck twice this winter in -20'C weather. The owners manual says NOT to use 10W30. Be very careful what your Mechanics are putting in your engine.

I noticed a vast improvement in the overall behavior of my 2019 Ram 25oo almost right away, smother quieter idle, better acceleration and fuel economy, the truck just seems to run happier, I've made it to 42K without any issues, I do run full synthetic Rotella T6 and change it every 10-12K and I keep up with regular fuel filter replacement, so far, so good.

    As for fuel filters, I only put about 5-6,000 miles a year on my truck, well below the required amount to change the fuel filter. I still change mine every November and April though.

      An old tried and true trick to add lubricity to fuel that works from what I understand can be used on an 06 or older diesel truck in the US of adding a bit of tcw3 rated conventional two-stroke motor oil to the fuel can work wonders. I have been using a 1/2 an ounce per gallon of diesel fuel in conjunction with a recommended amount of power service per gallon in my '06 5.9 Cummins since the day I purchased it in 2012. The injectors seem to appreciate it from what I can tell. As they are quieter the audible tick that they once had when I first purchased it is no longer there.The truck has also passed emissions with flying colors. I bought this truck a Dodge 3500 when it had 50,000 miles on it. It now has 110,000 and going strong no problems. Not saying you should do it but it works for me giving me the Peace of mind that my common rail high pressure fuel system is receiving some lubricant.

    • @repairvehicle
      @repairvehicle  Před 3 lety +4

      Fuel additives with lubricity definitely will extend the life of the pump. Will it prevent pump from failing, good chance it will. I personally have not heard from anyone who was using Fuel additive every fuel tank with lubricity and their pump failed. There are different Fuel additives, not every Fuel additive has lubricity. Regular cp3 pump cannot supply enough pressure that cp4 provides from factory. Cp3 pump must be heavily modified beyond it's designed basis. Once it's modified it can provide high pressure, however it's no longer regular well known reliable cp3 pump, its hybrid cp3 pump with unknown reliability. Do cp3 pumps fail, of course they do when contamination enters fuel and not enough lubricity. Question for you about converting to cp3 hybrid. When the cp3 hybrid pump fails on the road and you have to be towed to have it fixed, what repair shop is going to have cp3 hybrid in stock or will be able to find one quickly? Not many, certainly not ram dealers and they will tell you that you have to use cp4 as replacement. Also, computer system might not even work properly with hybrid cp3.
      If it was my truck, I would use quality fuel additive with lubricity every fuel tank, no skipping. Always use quality fuel filters from reputable reseller or directly from distributor. Change fuel filter per factory intervals. What is the best fuel additive for diesel, stay subscribed I will make a video with data as a proof. If I have not answered your questions please let me know.

    The CP4 is a poorly designed pump bar none! Bosch made one horrible mistake and that was not keying that piston with the roller in it's bore. You have to look at that piston as if it were a roller lifter which it basically is and all roller lifters are keyed or held in place by keepers to prevent them from rotating in the bore causing the roller to no longer roll over the cam. Bosch was planning on spring pressure holding it still but air can cause it to float around causing rotation as well as problems due to water and poor lubrication. I feel strongly that if Bosch had keyed that piston somehow, they would have possibly cut CP4 failures in half. The rest of the design is probably great and it is extremely modular and easy to adapt to many applications but I can't give it a pass due to that one major engineering failure. I definitely sleep better now that I converted my '19 Ram to run a CP3.

      @@repairvehicle I understand the lubricity issues, I ran Hot Shots EDT religiously every single tank and had success with both the CP4 in my Ram ecodiesel and the CP4 in my '19 Cummins. The point is, you shouldn't have to run these expensive additives to try to keep a pump alive. Which brings up another engineering failure of the CP4. It is using the same fuel that is lubricating it's bottom end to be sent up to the high pressure pumping components, so if the bottom end fails, metal shavings will be distributed to the fuel rail. CP3 sends bottom end fuel back to tank and high pressure pumping components recieve fuel that wasn't drawn from the bottom end therefore reducing the chances of shavings making its way to the rail.

The 2021s and newer with factory installed CP3 (CP-ISB21) no longer have overdriven pump gears. 19s and 20s will possibly make good candidates for performance upgrades due to that 1.5 times faster spinning pump.
