You're absolutely right about the alcohol eating fuel lines. The hose they sell that is resistant to the E10 is really pricey but you don't have to worry about your fuel lines falling apart. Anyone with older, collector cars, hot rods, classics should be aware of this and replace any rubber or neoprene lines before a disaster happens. It almost did with me. I'm a firm believer.
