2017 or newer F-450 issues

It's called cp4 bypass kit or disaster prevention kit.
Several mfgs now.
It doesn't make the pump last longer, but rather keeps the commonly failed parts from going downstream to the injectors.

what is the proper full term for the bypass kit and how would I go about asking for one to be installed. I am not fond of any dealership IF they would even do that sort of thing.

is this considered a major alteration? I'm guessing any after market / performance diesel shop can get this?

this is good information, thank you!

Well having had a 2011 F-450 for 175,000 miles with only a couple of oil leaks and now having a 2019 F-450 with 28,000, no issues. Never a fuel pump issue since 2001 was my first super duty.

You would be shocked at the difference a couple of generations make.

Would do it over again.

I suppose it depends on how long you intend on keeping the truck. If only a few years where most of them are under warranty then the CP4 pump is likely less of a concern.

Myself, I plan on keeping my truck for a very long time (likely until death do us part) so the long term cost of ownership and repairs was important to me. I just couldn't bring myself to chance playing Russian Roulette with the CP4 when at the time there were perfectly good trucks with the trusty CP3 (the Ram/Cummins used the CP3 until the new 2019 models came out).

My truck has almost 180k miles and almost 8 years old and has been out of warranty a long time ago and I'm still holding onto it.

If you plan on keeping your truck for the long haul be prepared to have it nickel and dime you as sensors and various materials age and start to fail. I recently had to have the evaporator coil replaced and last weekend I noticed by vacuum controlled front hubs stopped working and had to get out of the truck and put them into manual mode. I'll have to look at this issue if I want my auto hubs to continue to work.

I find it strange that we all know the cp4 which has been out for years is a ticking time bomb yet Powerstroke and Cummins engineers are dumb enough to contnue to install these faulty pumps on their engines without checking with us forum members first.

I understand you're dilemma. However, when you type in CP4 (just those 3 characters) and google "auto fills" to --CP4 failure in Powerstroke

I think that pretty much a dead giveaway that there's more problems with powerstroke and CP4 than with anyone else...for whatever reason.
