If you have so much water in your gas tank that your engine won't run adding a water remover will not help.
That is one of the reasons E-85 corrodes fuel systems, it has so much alcohol in it that is absourbs moisture from the air and carries it to the engine where as E-free gasoline would just allow the water to condense on the bottom of the tank and ride around harmlessly for decades.
Wow, that's a lot of misinformation......
Here I will break down your falsehoods by the number.
1. Not all gas sold in the US is E-10. There are plenty of stations that sell non-ethanol gas around, you just have to know where to find them.
2. Water does not "stick" to ethanol or any type of alcohol. Alcohol emulsifies with water and mixes with it; if that is what you mean.
3. We aren't talking about having so much water in gas that your engine won't run, that is a separate issue. Even small amounts of water will cause engines to not run properly though.
4. There are plenty of products out there that do a better job of treating water contaminated gas than ethanol. Pure, fresh, ethanol added to gas with some water in it is one thing. Ethanol that is added to gas at a local gas refinery weeks in advance and then stored in a less than perfectly sealed gas tank under a gas station for days, weeks or months at a time is a very different set of circumstances than what you are describing. K-100 fuel additive has been around for over 50 years, mostly in the commercial trucking industry. The makers of K-100 must really have the art of selling snake oil down to a science in order to fool (mostly commercial industries) people for that long. If that is the case, maybe they should quit bothering with fuel additives and write books about how to sell people useless products that don't actually work.
5. E-85 does not "corrode" fuel systems because it absorbs water. The real problems with E-85 come from having a fuel system that was never designed to handle that much ethanol. Rubber and plastic components begin to break down quickly if they were not designed for use with E-85. E-85 also has very different burn characteristics and the engine has to be tuned via an ECU designed to run e-85 or manual adjustments via an outside source (a person) tuning the engine. Water and its problems are one possible side effect of E-85, but not the real issue when talking about E-85.
6. Water at the bottom of the gas tank is hardly harmless. Most gas tank's pick up lines are either directly at the bottom or very close to the bottom of gas tanks, in most fuel systems. If there is water at the bottom of a gas tank, the water is usually the very first thing fed into a fuel system and that will cause problems if there is enough water down there.
