Would this work.
Air Vacuum Pump with R134A and R12 Connectors
Vacuum Pump - AC Vacuum Pump w/ R134A & R12 Connectors


how about these gauges?
Yellow Jacket 42001 Series 41 Manifold 3 1/8" Gauges: Amazon.com: Industrial & Scientific

how about this gauge or do you recommend a different gauge?
Fieldpiece SVG3 Digital Micron Gauge (Vacuum Gauge)
Fieldpiece SVG3 Easy View Vacuum Gauge - at the Test Equipment Depot

Not sure , but it sounds like it would consume a lot of compressed air ? I suggest , at the very least , buy the little electric vacuum pump . I bought one by Robinair , at a pawn shop 10 -15 years ago . When I put in the R22 central air system .

My mini split had the same size fitting on the service valve , that the old R12 & R22 systems . My old hoses and Gauges worked , but I had to do some interpretation on the gauge .

I bought a set of hoses and gauges at Harbor Freight , to work on R134a automotive systems . This has been several years ago .

God bless
