Thanks man yea that was not on there correctly and the vaporizer needed a rebuild

You need to make sure that you fuel hose connector is threaded on completely. There should only be a gap about the thickness of a half dollar between the coupler and the tank valve. If another tank was put on sometimes the square ring from the old tank will come out and sandwich between the coupler and the valve also not allowing the valve to open. There is a sensor on the line under the radiator cover panel.
