Zusammenfassung:	A method and assembly (kit) are provided for use by propane tank service personnel to detect escaping gas in propane tank systems. The standard connector between the regulator and tank service valve is replaced with a permanent valve assembly including a valve unit disposed in a branch connection of a tee connector. A separate pressure gauge is individually assigned to tank service personnel and adapted to be carried by such personnel in testing the pressure in the propane tank. The pressure gauge includes a hose having, at the distal end thereof, a valve unit connector for actuating the valve unit when the gauge is connected to the valve unit. When the pressure gauge is connected to the valve unit the latter is actuated to provide an immediate reading of the tank pressure. A determination is made from this reading whether the tank is out of gas, and if out of gas, the service valve is turned on, gas introduced, the service valve turned off and a further pressure check made to determine whether gas is leaking.
