What size of vacuum pump do you recommend? Do you think any old pump I can pick up at Harbor Freight will be enough, or does it have to be something particularly powerful?
Any one that will draw at least 27 hg. (inches in mercury) Harbor freight AC vacuums will work fine. I used that for years, recently upgraded to the Vevor two stage.
