I was thinking about trying to do the same trick (sort of) with LPG too keep
the tank pressure constant. I decided that it would proably be easier to
pressurize the tank with N2 or CO2 though. But I haven't getting around to
trying either yet. And I'm sure either of those ideas would break some rule
here.
