found in M800-HC4V's reviews: Handy little machine! - Because the fittings use air pressure to seal themselves, you can pull the line right out of the fitting when there is no pressure in the tanks. It just slips out of the O-ring in the fitting. There was a tiny chip of metal in the fitting causing the leak, so I just wiped it off and pushed the plastic line back in.
