On the issue of space. If your handy you could separate the compressor Hang the tank in the rafters. Put the motor and compressor someplace out of the way like under a bench. You really need the scfm more than the tank size, but you should get as big a tank as possible. You could always scrounge up a few 30 gal tanks and hang them in a row piped together. I know this sounds like a soup sandwich, but I'm a certified junkyard nutcase. At any rate good luck,,,,,,,,,
