First, if you want to store the gen for more than, say 2 months, then use non-ethanol gasoline with Stabil. The so-called ethanol fuel stabilizers will not stabilize ethanol to the degree you need it to. The ethanol will break down and turn everything gummy. The ethanol is water based and the water that is left behind will rust or corrode the carburetor parts.
Second, and this all depends on your generator fuel pump, if left in a dry state some things can dry out and crack/rot. I personally have a mechanical pump and the paper element/diaphragm dried out as well as some of the rubber o-rings. Some generators need to have gas in there to keep things wet.
Run the generator with non-ethanol gas for 10 minutes (or until it is purged of ethanol). You can simply move the fuel hose to a container with the gas in it, or you can purge your RV gas tank by running real gas for a while. I have an old push mower gas tank that I use to feed the generator gas when I will store it.
All said, the generator head unit also needs to be run regularly, so it is not ideal to store the generator for too long.
Where would I find a gas station that pumps non-ethanol gasoline?
Seems like they would be fined by the State EPA. I would like to run it in all my vehicles, pure gasoline no ethanol.
