I run what I have with E85, and just keep an eye on things. Purchasing new parts I tend to choose those saying themselves to be E85-compatible. Smaller bits and pieces used in my home-built fuel system I drop one identical part in a glass jar with E85 and just leave it there for the next few years, to see if anything is affected.

For shooting in the dark you can use +30% flow as guideline...
