E-85 on a 360

Well, color me surprised, just read through the corrosive section on the E85 site and no one seems to be having any trouble with it. Maybe there are some types that are worse or something, but they did bring up a good idea. Worst case just take whatever part you are concerned about and let in soak in a bottle of the stuff and see what happens. I would be mostly concerned about the old rubber hoses, but a lot of people seem to be getting by without any problems over several years. I know O rings and stuff tend to swell pretty bad when exposed to it, which would be my main concern, but you could just drop a few in a jar of E85 and see what happens.
