This chart shows Tygon as "unacceptable" for use with ethanol, and all alcohols in general.

The LP1100 that Lubemaster pointed to has a liner that is ethanol compatible (most likely teflon).

That same chart shows tygon being unacceptable for gasoline. I don't think that is the fuel line tygon. There are numerous types. Temp rating is sort of low, though.
