What do you use for a vac pump, single or dual stage? What vacuum level do you get it down to? What do you use for a vacuum gauge to see the level achieved?

Single stage commercial . Have calibrated gauge and at 1100 asl I see 29 inches. If you hold 29 for some time and run the engine to full temperature you can be sure that whatever minute amount of water vapor is in the system is absorbed by the desiccant....or so small a volume it will not ice anywhere..
