OK, I did some testing again today by first pressurizing the whole vacuum system, No apparent leaks.
Second, connecting the lien from the pump directly to the modulator, no change, still 10 inches.
Next measuring on the pump with the whole system in place, still 10 inches.
Finally, just the pump, kind of bumpy, but 10 inches on avarage.
To me this means the pump is no good, do you all agree?
I can pick up a rebuilt one at noon tomorrow, so than I will be sure.

It would be nice if you had a little more vacuum.

The pump is bad. Mine went out in my 97 Chevy truck. Since it only operates
the waste gate, I made a new waste gate controller for 5 bucks.
