I haven't noticed any problems with Edelbrock carburetors that I've had running dry. 27% ethanol is a lot. I have seen check valves that you can put in the fuel line to keep it from running back into the tank but as Dave mentioned you have one in the fuel pump. Depending on where you are putting the electric pump you may have the same issue if it's related to the amount of Ethanol in the fuel. If the fuel is evaporating even an electric pump may not totally solve your problem.
