Don't be completely suprised if it doesn't hold a vacuum overnight. I worked in an auto repair shop for almost 25 years and would fairly often have an AC system that would not hold a vacuum for a half hour. 95% of the time there was no leak to be found. I always assumed that some compressor seals hold pressure fine but will leak slightly under vacuum. Patrick
