I'm curious to hear this story, as I've had a partially pressurized system blow up on me. Also, those valves fail like fucking nobodies business. Replace a low line on my old Civic and it held charge for the last several years I owned it. An $80 part increased the car's value by $500 when I resold it because the AC still worked.bought a hose and r134a to recharge the AC, all i know is look for "L" and avoid "H".
