Yes, I understand. I am still having trouble wrapping my mind around how that can be what I am looking at in my truck. I have my 95 right beside it and can easily see the rear plate and snap ring but just cannot see where it would go on the 2002, but other than looking at these two pumps since this failure, I have exactly "0" experience with anything involving the HPOP. I have accumulated almost a million combined miles on 3 seperate trucks and have never had anything more major than a water pump. This will get fixed and I will be rolling again soon. These trucks are awesome.
I will get the fuel filter bowl and all of the other stuff off and out of the way tomorrow or Friday and see what parts might be in the valley. Sounds like a new pump is in the near future.
I will post pics of what I find when I get to the root of the problem.
Thanks for the help.

Here is a link on removal and re-installation of an HPOP. It is for a 95, but as you know since you have a 95, it is essentially the same. I'm looking forward to your post on what you find. Good Luck.

Kris,
After looking at your pictures, I can really see what you are saying about looking into rather than at the pump. What I am seeing looks a lot like the pic of the pump with the plunger cover and bearing removed.
That is not really what I wanted to find, but it is whatever it is I guess. Sure was hoping for a split o-ring though.
Payson , Thanks for the link to the removal instructions. Funny thing, I actually printed them out when I ran across them during an earlier search. They look like they will be really helpful.
Now I just gotta find the time to get into it. Between having a full time job, feeding 4 kids and 250+ cows, this really is not a convenient time for this to happen. Good thing the ole 95 with 404,000 miles is still around to fill in till this one gets back up and going.
Thanks for the help, I will keep you posted on what i find.

Okay, Curiosity got the best of me and I went back out for another look.
Kris and Payson hit it on the head, I found the snap ring under the y pipe and I beleive I can see a little bit of the rear cover from where it is hiding back near the turbo. The internals of the pump that I am seeing as you guys suggested is hanging out about a half inch and will not budge in or out with the little bit of grip I can get on it with everything in the way. I guess I will start shopping for a new pump and get it swapped out. I am sure there is no need in trying to salvage this one.
Thanks Guys.

Good luck with the new pump install.

The plungers on the barrel are not much more than a half inch long. If you are familiar with how it works, the swashplate is fixed in the rear half of the pump, the barrel rotates in front of it. The 7 pistons are loaded into the barrel, and as it spins, the heads of the pistons are fastened to the swashplate via a snap-ring like plate, and thus moves the pistons in and out of the barrels as the barrel rotates. The pistons moving in and out displace the oil. At one point, one of the pistons is almost all the way out of its bore, but in just enough to suffice. If that is pushed out a little bit, one or more of the plungers is out of the bore possibly. That soft brass barrel assembly doesnt take much to mangle it beyond use, and at the speed it spins im sure it made some damage.

After looking at the pictures of Kris's pump disassembled, I was kind of afraid that the guts would be mangled by the way mine came apart. I will give it a good look over but I am still planning on replacing the pump simply because it has 200,000 miles on it and I will have it off anyway. I would feel more confident in that I think than hitting the road with this one pieced back together. I know anything mechanical can fail at any time, even brand new, but it would give me a little piece of mind.
I will try to post pictures of what I find when I tear it down and look at the damage inside.
