Thanks for the advise guys. I was not trying to run the compressor with the vacuum connected. I had connected the vacuum pump as suggested to evacuate the system, It immediately brought the low side gauge to full vacuum, I let it run for about an hour. I then disconnedted the vacuum pump, by removing the center yellow hose from the vacuum pump and attaching it to the center secondary fitting on my gauge set. I then opened the low and high side quick connect valves and the low and high side gauge valves. there was a quick sucking of the yellow hose air from disconnecting it and then the vacuum stayed at greater than 29mm Hg for at least 30 minutes. This told me there was no large leak.
