Review on 🔧 Efficient FJC (6909) 3.0 CFM Vacuum Pump for Effective Air Removal by Joe Roberts

This pump did the job and when my gauges were correct it lowered the vacuum in my air conditioner to the correct level . I worked the pump for a total of about 90 minutes. This is my first time using this pump and I bought it new. The oil level will drop significantly, so you need to keep a close eye on the oil lever if it's been used for more than an hour. I was surprised to see that the level had dropped at least a quarter from the full line.
