Turn it around, Gig.

Look at it as a safety feature.

Ethanol in the fuel might absorb any water in the tanks
avoiding an engine failure.

That's what all those drains are for. My little 601 will have three places
designed to get water out of the fuel before it gets sucked in to the
engine.


Richard's poiint was well worth noting. AFAIK, in automobiles, wich
generally have no drains, when a problem of water in the fuel tank is
encountered, it is normally resolved by adding alcohol. One of the other
alcohols is normally used, because of the beverage tax applied to pure
ethanol; but, according to my local mechanic, that gets the car running so
that the fuel can be successfully consumed in the normal way. At least in
theory, that would result in a slight and temporary reduction in horsepower;
but it is hard to imagine a situation where the loss would exceed 5 of 10
percent--even on a carbureted engine.
