3.1416 X 22=69.1152 inches of area. Air pressure is your choice.

I'm not advocating any method of removing combustible fuels from a drum, except for the safest one.

Liquid gasoline is not flammable, but the vapors that come off of it certainly are. the dicey part is, it changes from a liquid to a vapor really, really fast. So, please be safe. A burn victim is likely the absolutely worst way to suffer.

Ken, to square the radius is not add it. You must multiply. 11 X 11 = 121 not 22 as you propose.
I again say it is not a good idea to pressurize a barrel which is not rated as a pressure vessel.
If using air pressure to move gas out of a vessel/tank is such a good idea why don't gas stations and truck stops use that method?
To the best of my knowledge all gas stations and truck stops use pumps.
