accessories for my air compressor?

Question

Hi,I'm juta dumb homeowner, so please be patient & excuse any ignorane onmy part.I use my handy-dandy Craftsman 150psi air compressor for lotsa thingsaround the house. I'm wondering if anyone makes attachment to:1)  allow it to run a light-duty liquid pump - for pumping smallquantities of water or whatever.2)  turn the compressor into a reasonably-powered vacuum pump - for"dry" applcations like evacuationg a/c systems or watever.I'm sure I've seen these accessories before, but now that I need 'em ofcourse I can't find ' will be MUCH appreciated!best,JohnB
