On civilian 6.5's the CDR sits on top of the passenger side valve cover. I have looked and looked but cannot figure out how the CDR is plumbed on military engines. No hole on the valve cover. Any insight from anyone here would be helpful.

All, Its been a while. I'm trying to determine when and what vehicle the DS2831-4911 injection pump was used. I could not find anything on the sticky or on a search thru the threads. Any help would be appreciated.

So I have an opportunity to purchase a 6.5 core motor with all of the injection lines, manifolds, injection pump and accessory brackets. They got the motor out of the truck, a 92 or 93. The block casting number is 14022660. Underneath appears 3-2-81. So it would seem to me that this is a 6.2...
