Marv, that sounds like the technique that chemist use to identify substances. They basically run it though a long, extremely thin tube. The heavier elements is pulled to the tube walls and slowed down. A detector at the end of the tube gives an indication of what comes out when, and produces a 'signature' of different chemicals. I would say that water, in the form of very small droplets vs molecules, either has a hard time getting through a .010 opening or condenses on the walls before getting through (the glass is installed with the tube pointing down, right?)
Something else to thing about. The tank will need a vent that can suck enough air to replace the fuel that is being burned, else you get back pressure and the pumps will stop pumping. Jim's manual method will work, but I would definitely be afraid that the cap would be forgotten at some point. The back pressure is guaranteed not to increase enough to stop the pump until you're 100ft off the ground.
