|Yea.. I am not too thrilled with the air compressor idea. Even though
|the compressor unit I have is from a portable window unit air
|conditioner. This compressor is rated at 200 psi Max (they can go much
|higher) so with a pressure relief/regulator I should be OK. And then
|there is the problem with removing the oil that is pumped into the
|propane tank by the compressor.

Orient the tank so it drains back into the compressor.
