As has been mentioned occasionally, this is not a good idea. The gasoline without ethanol will have a much lower octane rating and may suffer other combustion-related problems. You'll also likely end up with some of the water remaining behind.
I don't want ethanol in my gas, but I'd rather have ethanol in it than water!

Guys,
Think about this: EAA Test for Ethanol
HOW TO USE THE TESTER:
1. Add water precisely to zero level line on percentage alcohol scale on side of tester.
2. Add fuel to be tested up to the gas level line.
3. Cap with thumb or stopper provided, shake vigorously to thoroughly mix.
4. Let stand 5-10 minutes, read percentage alcohol-in-fuel on scale of 0-30% at line separating gasoline and water.
5. The gauge on the side of the tube will read percentage of alcohol in the tube.
The way this test works is that you add an excess of water to the fuel and the alcohol migrates into the water, thus separating from the gasoline fraction. 5 gal = 18,927 ml and 10% of that would be 1,892.7 ml of alcohol or slightly less than 2 liters. Rather than going to Nevada why not use local gasoline and separate out the ethanol portion, filter the gasoline through a filter that would remove any remaining ethanol and use the gasoline in the aircraft. Agitation and decanting of the gasoline off of the water portion should be easy to do. At $4.00 a gallon here on the east coast it would be a 40 cent loss over the pump price but would be cheaper than 100 LL. Do in 50 gallon batches as drums are readily available. (Flame suit on)
