I contacted Triumph about the Ethanol/E10 fuel and its possible effects on plastic fuel tanks. Triumph contacted their fuel tank supplier and received this response which they forwarded to me:

"I have copied and posted in RED here the important parts of the emails that have gone back and forth.
Here is the answer to your question: "Are you aware if Triumph’s fuel tanks and parts of the fuel tanks can and will withstand the use of E-10 ethanol fuel?"

Answer:
The Energy Policy Act of 2005 requires ethanol production to nearly double in the US by 2012. The EPA, which is responsible for setting Federal Guidelines that regulate fuel content, is allowing a 10% ethanol and gasoline blend for common engine use: percentages higher than E-10 are currently prohibited. The potential effects of E-10 and E-85 fuels on existing marketed products remain one to be wary of:

1. Ethanol is hygroscopic, mixing more easily with water than gasoline.
Fuel Tank Shell will not be impacted.
May lead to serious damage to some fuel system components- regular
maintenance recommended.
2. Ethanol increases fuel electrical conductivity.
Promotes metal corrosion of system components
Most of the "molded in inserts" are encapsulated thus a non issue.
We are waiting to hear back from our sending unit companies to validate their senders are E-10 compatible.
3. Ethanol blends, such as E-10 affect the integrity of some gaskets and other non metal materials.
Can cause common materials to swell in excess of 35% and shrink by 6%.
Already working on improving our pick-up tube material to provide
greater compatibility with blends.

With this being indicated fuel systems going forward will need Water separation filters, which Moeller Marine can provide. This will reduce and minimize Ethanol related issues."
