I think alcohol is a polar-covalent solvent that tends to hold water in
solution with gasoline. I suspect instead of getting the alchohol out, you
would be suspending water in the fuel that you would not be able to drain.

On the other hand, if you have an engine that can burn alcohol, perhaps some
amount of water in the alcohol could boost the performance of the engine ala
water injection in old military aircraft. You could turn some of that
wasted heat into steam before dumping it out the exhaust.

I was wondering if it is possible to remove the ethanol from mogas and
thought of the folling idea.
Alcohol binds with water.
Get a big tank with a spigot at the bottom, fill it with mogas.
Add water, aggitate, let sit.
The alcohol ladden water will settle to the bottom.
Open the spigot, drain the water.
You now have alcohol free mogas.
What am I missing here?
