Ethanol and MFI?

Can MFI be modified to run on E85 or alcohol without changing the whole character of the system? If a 2.2 911T pump can be richened to run a 3.0 RS spec, can it feed enough fuel to run a 2.5 or similar displacement on alcohol?

This thought was sparked by a similar question on the Turbo forum that decided that CIS would not handle the richening.

The water in ethanol/alcohol will destroy the internals of the pump. Not sure how long it will take but your pump and injectors may not be happy campers. typical changes to fuel systems for alcohol are anodized aluminum and steel replaced with stainless or plastic.
