Stabilizer will not remove the ethanol - it has to be physically separated from the "gas" (if one can even call it that anymore) mixture. You can build an extractor for this purpose (or just find a "0E" gas station).

The stuff being sold as "gas" today is pure garbage. I have little doubt it cost me my 951 (engine fire - rubber fuel line degradation) a few years ago.

There might be some kind of chemical that would have more affinity for ethanol than water or rubber (hydrogen bonds?) but I'm not aware of any. I've seen some blue stuff in marinas that's supposed to help but have no idea what the chemical theory is behind it or whether it even works.
