I'm also curious about the state of this build. I'm looking at building a pure mechanical Cummins for a 1972 application, and have been exploring options of just using a "stock" (it won't really be stock, but you know what I mean) 12v with p-pump, fitting a p-pump to a 24v 5.9, or possibly even doing something like this.
Does the 6.7 not have an engine driven lift pump like the VE 12v does? Is that why you need the M35A2 fuel pump?

Very interesting! Not to be ignorant, but why couldn't you just drop an 8.3L (6CT) Cummins in it?
Definitely a neat build though!

|Chigger||I'm not sure how much in volume. I know on the M35A2, the pump can easily pressurize the fuel to 60-70 psi at around 2500 RPM. It is a big gamble to see if it works on my Cummins engine. I suspect that it is more than enough fuel. The excess will just go through the relief valve and back to the tank.|

|Chigger||Finally, here is the finished product. Hopefully I will have some time this weekend to see how well it runs. The beauty of the M35A2 fuel pump is that it has an internal bypass. This means that I can temporarily use an in-tank pump to prime the fuel system if there is any air in the line. Once the line is primed, the pump can be turned off and the motor should run with only the mechanical pump.|

|ganzey||HOLY CATS!!! you are doing some amazing work in this thread. as you stated, its probably not the best idea to ppump a 6.7, but god damn, you are making that engine your b!tch!|
