Call Cummins with your ESN and see if there is a ReCon pump available, just to see if there is a big difference in price. It will be"stock" so you will need to tinker with timing mods.

Hey Mos, you still out there? Making any progress?
I’ve been trying to make progress, but I’ve been waiting on the pump shop. Actually called them this morning and got bad news. Apparently there was a problem with something called anerobic or some crap and I guess it is a part that isn’t sold as a replacement. To top that off the guy that works on these pumps is on vacation until the 7th, so I won’t hear anything until after that. They said they already tried to reach out to other shops, but have had no luck. I guess when that guy gets back they’ll go through their boneyard and see if they have anything serviceable.Hey Mos, you still out there? Making any progress?
that would be an aniroid also known as an afc or air fuel control some folks call it a smoke valve to it adjusts the fuel rate to match boost and helps limit extreme smoke under acceleration.I’ve been trying to make progress, but I’ve been waiting on the pump shop.

Other than that, all I have to do is weld up a new intake shell and the rest is a waiting game. Going to need the truck soon though as I know my roads are nasty during the winter.
Give me a call so we can work out details - 928-350-9048 if I don’t answer just leave a message and I’ll call back when I have signal (I’ll be out in the woods cutting firewood)I have two Bosch P-7100 "P" pumps. One is off an 8.3L, and one is off a 5.9L. I am keeping the 8.3L one until I have my ISL conversion complete. I would sell the 5.9L one immediately. It came from a truck salvage yard, with a 90 day guarantee, so it should be good. The only difference between the 5.9L and 8.3L Bosch "P" pumps is the way oil is fed to the injection pump. With the 8.3L, there is a very small hole in the back surface of the timing cover where the pump mounts that feeds into the injection pump. On the 5.9L, the pump is fed by an external oil line (you could easily do via a tee off the oil pressure sending unit, or any open oil pressure galley port). They both drain back the same way, which is simple overflow out the front roller bearing (no seal) and spills into the timing cover. This is why it is important to fill the pump with oil first, because the fill flow rate is kind of slow (possible restrictor in line), so you don't want to start it dry. I think the 5.9L pump simply blocks the oil feed hole in the timing cover, or you could plug it with a gasket or pipe plug threaded in flush. The 5.9L injection pump mounting gasket probably plugs it by itself. It is very small diameter, so pretty low total pressure on it. People have put 5.9L pumps on 8.3's, and vice-versa. You can check some articles on the Dodge forums for more info. I stopped once I saw it can work both ways pretty easily. They are both 12mm plungers and barrels, as to where our Bosch MW pumps are 10mm elements. This is the difference in power capability (about 300hp vs 400hp of fuel flow). You may also be able to simply drill the hole in the face of the 5.9L pump, and cap the external line.
The P pumps are capable of 400hp as-is. I'd hate to see you install it, get excited, slide the fuel plate forward, and have all your rocker arms fall off again.
Sorry these pumps are not cheap. I'd go less than market though, $750 for the 5.9L "P" pump. They are typically +$1,000 used with no warranty. I'd offer a refund if it did not work out for you for any reason. Would like to see your truck operational and you enjoying it. I think you'd be the first one here with a P pump M939a2. Then there would be two of us that could eat Simp's lunch.
