Regarding ethanol-free gasoline, we use a smartphone app called Pure Gas. It works nationwide.
We use two gas stations that have ethanol-free fuel. One is a gas station / smoke shop. The other is a farm co-op.
Both are totally ethanol-free, so there is regular turnover of the product in their tanks.
Aside: We frequently take a supply of 5-gallon cans in our Nissan Leaf to go get gas for the mighty Mopars we're working on.
We figure our electric car has likely been to more gas stations than anyone else's EV in WA.
