Yes. They have a ton of failures of the CP4.1. If you don’t know, don’t argue.

A hundred thousand miles is not a lot of miles for a 2011. That aside, maybe you have the special edition sprinkled with the Ford pixie dust IDK. And good for you if your not worried, however you will not change the minds of people who have been burned or have friends who’ve been burned by...

Leds should never be used in low beam halogen reflector housings because they blind people, just like HIDs.

Whether you have duals or quads on your 12, the 2013+ projectors will be a huge upgrade in safety. They are way better in lighting up the road. I’ve driven a 12 and a 15, so I do know the difference. Bare in mind, if you do this swap, you’ll need an adapter harness.

So I had my login still active from checking something on TechAuthority... Looks like it is still a CP4.2. :( Well it was a good thread guys.

3/36 is supposed to be bumper to bumper.

I have a thread on the other forum where I am doing a few prototypes for a kit for the Cummins CP4.2. So far, I’ve tested and verified the fitment on the pump. I am experimenting with different designs. This is new thing for me, but with some trial and error and the perfect test truck, I may get...

When you have had friends die of covid, it gets real all of the sudden. Likewise with pumps.

CP4 is a general name. The .1 or .2 indicates the number of pistons the pump has. So the CP4.2 has two pistons. EDIT: R. Taylor beat me to it As for the pump, it’s is just a bad design. Talked with Bosch certified techs that work on VW, Audi, etc. and they know that the pump is just poorly...

If tuning isn’t changed, and the CP3 is modded to match the performance of a CP4, emissions output doesn’t change. There are a few reasons why CP4 is used. It’s newer, cheaper, lighter, and able to produce higher pressures. Unfortunately, the drawback is its reliability.

If Industrial Injection can install a CP3 on a Cummins with the timing case and tuning designed for the CP4, I think Cummins would have no problem doing so... This is also not a new engine platform, rather it’s just an upgraded ISB. I really do hope this information comes to fruition. It would...

2019+ Ram dually trucks have the larger 8x200 pattern.
