That "square" nut is NOT to relieve the pressure while filling. That is called the 80% valve. YOU ALWAYS OPEN IT WHEN FILLING, NO EXCEPTIONS. The reason you open it is because, IF that 80% valve spews white liquid LP while filling you STOP the fill. The LP tank has reached its 80% liquid capacity. The Auto Stop devices sometimes are not that accurate. NEVER rely on the Auto Stop valve to stop when filling. What you have experienced is the difference between states that regulate and license LP fillers and repair technicians and states that have no regulations. I live in a state(Texas) that heavily regulates LP and Natural gas and from my knowledge and being licensed by the State for 36 years agree with the laws and regulations. It makes us(Texans) safer. Too bad all states do not regulate LP and Natural gas. Doug
Doug, Great info to learn here. :)
