Review on 💨 Robinair (15310) VacuMaster Single Stage Vacuum Pump - Efficient 3 CFM Power for Superior Performance by James Stevenson

Received the pump yesterday. Appeared just as I was finishing installing a new compressor in my wife's car. Only used once but serves its purpose. Pulled the vacuum out of the system in less than 10 minutes. left it on for an hour. Check the oil level in the sight glass regularly. never went down The heating of the radiators turned out to be less than I expected. Warm but uncomfortable to touch with bare hands. This pump has 2 inlets. 1/4 torch and 1/2 acme. Newer gauges use Acme, older gauges use Flare. I didn't take that into account when ordering. Luck was on my side when my old set was torched. It's not a $200 pump, but it weighs less than a $200 pump.
