Even easier (and safer) would be to put down a hose from a compressor,

A compressor does not pump enough cubage. They are intended for pressure.

Mine pumps about 11 cfm at about 120 PSI, continuously. It is about
100 CFM uncompressed. I would say that it is quite a bit. After a day
of pumping, it would pump 144,000 cubic feet of uncompressed air. For
a 500 gallon tank, which is 70 cubic feet, the day of pumping is 2,000
times the volume of the tank.


Assuming it's rated honestly, your compressor pumps 11 SCFM of air at
atmospheric pressure and temperature when it's delivering 120 psi at the
outlet - closer to 200 air changes.

I'd also reconsider drawing a potentially explosive mixture into the
compressor where it will be compressed and heated. If you really wanted
to do this (I don't think it addresses the OP's concerns, and I'm not
recommending it), drawing the fumes through a gasoline engine might be a
safer approach.
