I don't see how installation is easier. You've got to dig just as deep to remove the failed CP4. So no time savings. I guess it would be a time savings if you ever had to replace the included CP3, but if that is the case then this is not the kit to go with anyhow. And what about those hard fuel lines? How do you reroute those without breaking or bending them? And now your fuel pump is belt driven? Hmm... I don't know fellas....
I like that they mostly use factory fuel lines. My buddy had an issue with the DCR conversion fuel lines. When he finished up the install he found a leak. I guess it was at a join on a fuel line. S&S sent him a new fuel line. Im interested how much this is going to cost.
I know there is a lot of fear mongering but has anyone known anyone that's had a timing gear slip? Dave's Automotive acts like it happens to every 6.7 he sees. He's also very biased against Ford and seems to coddle Cummins.
not convincing need cp3 is better than cp4….my prior f-450 had a cp3 in it and there was always had metal glitter in the filter
The CP3 pump is better than the CP4 in terms of reliability and your prior F450 had a Siemens K16 pump from the factory which is totally different than the Bosch CP3, unless you did a CP3 conversion kit of some type.

The CP3 is a very reliable pump and I would think the load on the serpentine belt would be way less than the AC compressor. I'm not an expert by no means, but extreme high horsepower diesels typically have a secondary CP3 pump running on the serpentine belt so this is nothing really new.
Well golly that is an interesting way to do it. I wonder if it was a Cummins or Duramax based CP3 and how it will like being effectively overclocked in the long haul.

To the best of my knowledge there is NO way to retrofit a CP3 onto a 6.4. It was K16 only and K16s did seppuku themselves, not as often as a CP4 but they did do it. And the kicker was the fact they were on the BACK of the engine so cab off to get to it.

Looks to me as if the CP4 pump would remain in place, otherwise there would be a big open hole in the back of the timing cover.
No installation instructions, but looks to me like everything is still on the engine in that pic, just added the new pump and re-routed fuel lines.
As to the hard lines, shows to come with new hard lines to adapt the new pump, no re-routing the stock lines, just adapting them to the new lines.
As to the belt drive, they are pretty reliable so long as they are well aligned, plus a spare belt is easy to carry with you.
We'll see what's what when they show some installs and post a price.
This piece seems to replace the CP4, I think. Looks like a manifold so the factory lines stay in place and the two lines in the picture run to this manifold. I'm just not sure what the purpose of the shaft is unless it runs to something on the front side of the engine? I'm not familiar with that area so not sure.
