Re: [A/S] Another Propane Cylinder question

Hi, Jim 
  If you start with a new empty tank or one that has been revalved, 
and the valve is open and you attach the fill hose to it and pump in 
liquid propane to the 80 percent of the water capacity of the tank, 
where does the air go? And if the 20 percent void doesn't have air in 
it, what is there? A tank that is over filled will sometimes freeze 
because liquid propane gets into the valve. Thanks Arnie
