If you use garden hose make sure you use either 5/8" or 3/4" hose. Larger I.D. means less restriction for the compressor, = less heat which = longer compressor life.

Personally, I'd use the black flexible poly hose like they use for drip irrigation systems, only 5/8" I.D. insted of 1/2" that is sold in the big box stores around here.
