It's just a discussion. Instead of worthless comments, explain why it wouldn't work.

I agree. There isn't anything online anywhere saying "yay" or "nay" for our trucks. There is a bunch of stuff saying "yay" for the TDI VWs. Just nothing on a 6.7 or LML D/Max.

Accurate is on over at the .org answering questions, I know some don't like that forum but whatever. I'll see if he could get an account here to do the same. For now, here's the link to the post

On edit: It does seem like a good design and idea. I'm not so convinced it's a gimmick anymore

If there was a way to isolate the low pressure fuel chamber of the pump from the high pressure chamber so the high side only received fresh filtered fuel, the injectors would be protected. I don't even know if that is possible.

BTW this is exactly the principle of the kit. They are "bypassing" or blocking the passage from crankcase to the high pressure pump side and returning it all to the tank. Then the inlet/suction of the high pressure side pulls directly from the filters and electric lift pump.

There is no Cp3 conversion. CP3 won't fit. We tried. closest we ever got was gutting the cp4 and running 2 big ass cp3's..... Works well.

The problem is CP4s are junk when the flow demands are increased. Just because you give another path for fuel on the low pressure side doesn't mean the high pressure side is protected from failure, which will still wipe out the injectors.

Has there been instances of piston failure (high pressure side) in these pumps as well?? I was under the impression the only mode of failure seen in them so far were the roller cam/follower part. At least that's the high wear part that I see

Also would this heat up the fuel in the tank quite a bit by running it from the pump back in?

Which is the more prone failure point? High pressure side or the low pressure side?

The cam and follower eat **** so I would say the low side.
