Theres a way to remove ethanol from fuel. I know a guy who does this for his vehicles. Unfortunately you will need containers to do it.
Basically you get a container almost full of gas, pour water in it, and mix it around a bit/wait. The ethanol loves water and will come out of the fuel. This is basically forcing what happens with vehicles that sit with ethanol fuel for a while. Condensation forms, pulls the ethanol out of the gas and it pools conveniently at the bottom.
A huge inconvenience but it may be worth trying.
