If Honda is putting in fuel line parts not resistant to ethanol, THEY could be liable. Not much excuse. Ethanol has been in gasoline since at least the ‘80s, almost mandatory since the early ‘90s.
What would parts be like that were strong enough to survive the corrosive effects of ethanol? Forget suing Honda, I want to sue big corn and the tyrants at the EPA and enviro-whacko groups that forced this crap on us.
