Leaf Blowers

I purchased a new 125B Husqvarna Blower in October of 2011. This week it would not stay running and was leaking fuel. Knowing that there is 2 year warranty on the blower, I called Husqvarna to find the nearest authorized Husqvarna repair shop and took it in for repairs. They were going to call me when the problem was diagnosed and instead called the next day, talked with my wife to tell me that it was ready and there would be a $35.50 charge on it because fuel related issues were not covered by warranty.

When I picked up the blower I was told that the fuel line needed to be replaced because it had deteriated from the Ethanol in the gas. My question is, Where in the warranty , manual or on the Husqvarna website does it ever say not to run gasoline with Ethanol or the results if you do? I called customer service at Husqvarna to no avail.
