I have the original 13 gallon wing tanks. they have never been installed or had fuel in them. There is a sticker that says they have been creamed from the factor. I know the cream is life limited. So these are my questions.
1. How long does the cream really last?
2. Do the new tanks from KF need creamed, or just no ethanol fuel?
3. Has anyone installed Aluminum wings tanks?

I have been planning on buying a new set of wing tanks and the aluminum header tank but then I have read that people still have issues with mogas and ethanol messing with the tanks which got me thinking that if the Rotax motors will run on mogas why haven't I seen metal wing tanks anywhere. My next thought is that if the new tanks are going to have issues as well as the old tanks I have maybe I should just clean and re-cream and use them. Thanks!
