This is embarrassing................
I posted this question about 15 months ago with the exact same statistics.
(My brain age is going to do me in!! Getting older is a challenge.)
Reviewing that post,
1. My gauges and pump do not work right.
2. The set from Auto Zone did.
3. I filled the system with $60 of 134a (7 cans) and it worked.
4. But we did not use the AC system due to limited travels last year.
Now the system is empty, so even though the -26 vacuum held for two hours back then, I still have a leak.
So I have a path forward.
Thanks to all that replied to my question. I apologize for asking my redundant question.
