oil leak

[randy4140]

Help, I know I have seen a tech article or something on my leak in the past, just can't seem to find it now. I have oil leaking from between my power steering pump and what ever the pump in front of it is? maybe a hydro boost pump? sits below the injector pump. As I have the truck torn down for body work I would like to repair the seals ect if avalable. Many Thanks in advance!!

That would be your vacuum pump leaking. Geno's garage sells the rebuild kits for them. Here is a link to the rebuild article.

You can also get the seals from cummins for less than $20.

We just bought a vacuum pump kit for $14 from Rock Mountain Cummins in Boise, ID.

Thanks to all, with a little searching after my post I found the tech article on it and ordered the kit, now I have the vac pump kit and the starter contact kit, now to get to work!!

Make sure the kit is the one which has the double lipped seal, there 2-different kits

Cummins Kit is a double lipped.

Might look at your tappet cover while you are in there. I knew mine was leaking and also thought the pumps were leaking. It all turned out to be the tappet cover by itself.
