Air Compressor Unloader Valve line keeps popping out...
The tube that goes inot the air unloader keeps popping out and air escapes. Unscrewed it re-aligned the tube with the brass thingy inside, screwed it back and .....turn on the compressor and....it pops out again? 21-gal upright oiled, 6 months outta warranty. Gotta be an easy fix? Anyone???
