I haven't watched an automobile AC  refrigerant evacuation, Elliott, but
I've observed other refrigerant recapturings (HVAC stuff), and the process
is a hose hooks into the system with a pressure tolerant connection and
leads to a pump.  Output from the pump goes into a tank through another
pressurized connection.  You cannot see the fluids/gasses involved, but, as
I indicated before, you can measure the results by weighing the container
before and after.
