since i just put two new aluminum taks in mine- 55 gallons each- i also replaced all my fuel hoses, fill,vent, and supply- im not sure if the old fuel hose was always marked as fuel/alcohol but all the new fuel system hoses are. i was pleasantly pleased to see fuel/alc stenciled on them when I bought them. those 20 year old tanks that i replaced were shiney as they could be from running that ethonal blend in them. craig
