I know that ethanol has wreaked havoc on 'glass tanks in the past, but at Barber this year I was talking to a vendor and she SWORE that their new resins and liners will stand up to todays fuels.
I can't remember with 100% certainty, but I think it was the Legendary Motorcycles booth (someone correct me if I'm wrong. They had a booth set up at the bottom of the steep hill in Aces Corner).
She even said old, unused tanks could be used with their liner. If it ever had gas in it, it must be THOROUGHLY cleaned, lined and even then they couldn't swear it would last, but she felt you had a good chance.
Anyway....current experience with 'glass tanks and ethanol laced fuel? I think we get about 10-15% ethanol around here.
What brand tank? How many miles? Any special precautions? I'd love to hear your experiences.
