    Guy I used to work with thought he pulled a serious vacuum in about five minutes but his gages weren't tight enough onto the port to depress the schrader valves. Haha

    Don't new PSC motors have a polarity lock on them. I can't get the new ones to run backwards and I thought they were made not to.
