HEET is nothing more than 95% isopropyl alcohol. Water and alcohol mix, so do gas and alcohol. So while it doesn't do so efficiently, it will run through the fuel system and burn.
One thing about using HEET to disperse water is as it cools off, the HEET water mix forms a jelly. Make sure you change your fuel filter as soon as possible, as they will catch this stuff that might pass through fuel lines but not a filter.
PS:we don't have that problem in Minnesota where all gas has 10% alcohol in it. Except for Non-oxygenated that is spendy.
