I had three choices of vacuum pumps from the local suppliers.
NAPA, probably Beldon from unknown manufacturer.
Cardone reman.
Dorman new.
I chose the Dorman for $136.00
The Cardone reman was about two bucks lower.
 
Want to set that thought in stone? Go meet up with 1 or 2 people that have them installed.

If (hate that word) the trans shifter,xfer shifter and e-brake were located elsewhere in my Hummer, I would have custom made a doghouse that fit the ATT and had exhaust running down where those 3 controls are.

Currently considering making an extra large doghouse to have mount over the trans bell housing and exhaust down along side trans...

On pump: remeber 5% discount also.

I did check with Rockauto first thing. Ended ording from the local store, I guess I would not have really needed the pump for a week or so but just want to get the pump changed out and then see how the boost does.
I just hope the dorman holds up as good as the original pump that is now on the truck.
 
Finally, I got BOOOOOST ! ! ! !
Now, when getting on the diesel pedal good and hard, the truck jumps and so does the boost gauge, almost to 13 pounds, then settled to about 9 pounds.
When pulling a fairly steep hill at about 70, there was just a little bit of black smoke, the the TCC disengaged and the smoke went away. It was pushing close to ten pounds of boost.
Before boost, there was a huge cloud of black smoke emitting from the tail pipe.
Now I`m curious as to what the fuel mileage is going to be.

Are the A/C Delco ones new or reman , looks like new but not sure
 
On Rock Auto I think the Delco brand pumps are new. There was also listings for reman`d units.
I looked round on the net, thought by chance i could find a new diaphragm unit for my old pump, could not find them. Must be made of unobtainium.
