So, I've been looking at those surplus military injection pumps on Ebay, the ones that are $35, Stanadyne DB2829 4523.

I've also been reading that these military IPs are heavier duty, and that they have metal parts inside that can handle different types of fuel, just in case. This really appeals to me, what with the new ULSD fuel. Of course, I can get Bio locally, but, still...

My truck is running OK now, but at some point I plan on putting a new IP and injectors on there...I'll probably never be able to afford a true heavy duty Diesel like a Cummins, so I plan on making this one about as stout and powerful as I can.

The rebuilt IPs out there run about 400-600 bucks, depending. Not sure about new, or just what "rebuilt" means on those.

What would a good, reputable shop charge for a quality rebuild job ? Anyone have experience with a shop that does this in the Pacific Northwest ?

Any other thoughts ?

Thanks, all.

There are reputable shops selling exchange pumps in the $325 range. In regard to military pumps - I think a Humvee pump would be my last choice unless it was new-old-stock. Humvees have a very high pump failure rate.
The HD parts you mention are used in some of the pumps, but not all. And, all they consist of is updated fuel-pump parts in the back of the pump. All the high-pressure parts are the same. According to test reports from the U.S. Army - the "arctic kits" that were added did not help at all. Biggest problem they have is pump siezing - or - engines that will not start when hot. All related to thin JP8 fuel, very hot conditions, and HUMVEEs overloaded with protective armour.

The pump number you mentioned should be as thus:

DB2829-4523 23500415 1986-89 HMMWV (Military) - 1.2 cSt C/K

The "1.2 cSt" indicates it has the "arctic kit" installed with the harder fuel-pump parts. It got that name since it was first offered in very cold northern climates where diesel fuel was mixed very thin.

For civilian use - the most common part to wear first is the fuel-timing advance. If you are using WVO - depending on how used - and how treated and filtered - it sometimes causes siezed or scored head & rotors.

$325 is the cheapest price I've ever heard of for a quality IP, but I am pretty new at these engines. What's the best deal going ? Thanks again...

I don't pretend to have any "inside" information. Some pump shops cut corners, some don't. I usually fix my own pumps - but. . . two winters ago - as routine maintenance - I pulled the pump from a J-code Suburban of mine. Ran perfect but the pump had over 200K miles on it. So, I pulled it all part and found some parts showing general wear and also some chipping on the cam ring. I priced the parts - and found - in this case - I could buy a exhange pump cheaper. So - I bought one from DIS in Lubbock, Texas. They were very helpful on the phone, the price was $325 and the pump works great. But, they are now under new ownership - and I don't know if that makes any difference. I see they now charge $435 - that's quite a jump. Best I can tell you is - when you see a price you like - call and ask them exactly what is, and is not replaced in their pumps. I've called a few places lately that advertise on Ebay - and it seems the words "new" and "rebuilt" don't mean the same thing to all people anymore.

Not knowing how injection pumps are put together...I'm learning about all this, still...I wouldn't know exactly what to ask a shop as far as the quality of their rebuilds goes. My engine wrenching world until last year had been with rebuild kits for Carter carbs and Quadrajets and stuff.

OK, I was looking at Ebay again. One outfit, "Diesel Care and Performance," sells rebuilt pumps for $265, one of which is marked HD, and sets of 8 injectors for $150. Any one know about these guys directly ?

Is it quality work, or cheap for a reason ?

Anyone else have thoughts on favorite deals for IPs for these ?

I have not bought from Diesel Care - but I did call and speak to them. I chose NOT to deal with them - but just maybe the problem is due to "regional" language. They were calling injectors "rebuilt" when in fact - they had NO new parts. They were calling injectors "new" when in fact - they were rebuilt with new nozzle tips. So, after that - I refused to buy from them.

Diesel Care is a scam. Inferior workmanship, cheap parts. Not authorized to build anything. They are not ADS members either like they claim. You have to be authorized to be a member. See for yourself. Search the member list here. > http://www.diesel.org/dealer/us.html

Notice how they list Ford reman injectors next to a new Stanadyne box. Stanadyne does not offer reman. False advertising.
