The stock corrugated hose is great, and would probably be best. In fact, I spent the $8 on a new one, but no matter what I did, I could not it on the pump outlet.
I got the hose and the clamps at O'reilly. They had them behind the counter. Fuel injection rated clamps and hose. Supposed to handle the higher pressure of an EFI system. I think any EFI rated fuel hose should be safe for e85. The clamps were like $1.50 each.
