None. I replaced my pump with a racetronix one since the car had a lot of miles on it and I was going dual pumps anyway. Nothing wrong with the pump that was in it and nothing metal, including the pump had signs of corrosion.

What about corrosion with plastic components or the tank itself? I understand ethanol can damage certain rubbers and plastics as well.

Nothing. The tanks and lines are completely safe. Ethanol worries are spurred on by the corrosive properties of methanol. Ethanol and methanol are completely different. There isnt a single thing that E-85 damaged on my car. One thing it did do was make for cleaner internals and softer carbon deposits that came off easily with carb cleaner.
