Could you elaborate what you mean by "used E85 in early '90s cars... long-term"?

Supras, All-trac celicas, all tuned on E85 for years and never an issue. Not with factory fuel lines or aftermarket. No issues with pumps either, even though they weren't "rated" for E85.
Most people are worried about the corrosive attributes associated with many alcohols, and attribute those to E85 as well. But ethanol is quite stable, and doesn't react to most rubbers or metals. They've been using ethanol in concentrations of 10% for many many years now without any issues with fuel eating seals. I'm more worried about water, and the way it can trap contaminants in the fuel and cause failure of parts. but I wouldn't worry about it eating seals and stuff. It just doesn't happen that I've seen.
