Ethanol will absorb some water, I think less than 1%, so it can remove some water from the tank vs regular gas. But, once it surpasses that small % it will then permanently phase separate. The alcohol will come out of the gas & merge with water as a separate layer on the bottom of the tank. It will never go away and must be drained.
So you are saying that the fuel pickup (at the bottom of the fuel tank in most systems) will refuse to pump this phase separated (lets say 95% ethanol/5% water) mixture through the fuel system? That has not been my experience. Ever heard of water injection?
A modern computer controlled fuel injected gas engine, if it can get started on the above referenced mix, will pump it through and burn it. It may run like XXXX until it's warmed up and purged, but it will run. I wouldn't leave it in the system for long because of the corrosion/gum potential.
On the other hand, if you get a real slug of water in the fuel tank, well, not much can deal with that other than a drain plug.
