I know guys with "flex fuel" V8s in other Ford products that still won't run the stuff because it eats up everything it touches, over time.
Never had a problem, ran that setup for a while; even when I converted to a return style fuel system I still used the factory intake and fuel rails. Never had an issue. When I made that conversion, the original stuff was super clean and no corrosion.

You will need to change your filter more often, at least in the beginning as that fuel for some reason cleans everything out real good. When I did my big build, the inside of my take was spotless.
