John another thorough job...just one question on all the air conditioning open components. Is there a reason that you did not cap them or duct tape the open ac components? Moist and contamination is usually a concern ....your thoughts.. . Thank you again for sharing your knowledge

Thanks G. I did cap them immediately upon removal. I just barely removed the caps for this video. This car is going to get a deep vacuum for several days before adding refrigerant to make sure any moisture is removed.

Would micron gauge usage be a "best practice" if moisture is a concern? I know from my experience sometimes equipment hoses, pumps, o-rings, oil etc are not up to the task.

Yes, that helps insure whether or not you have a deep vacuum, but even if you do not, you can preheat the system in a warm room or with the heater in the car to increase the boiling point of the water under vacuum. Even our 10 year old vacuum pumps at 4300 feet can boil water of the system temperature is close to 100 degrees F (37.8 C). The colder the system temperature the deeper the vacuum
