I am having the same issues. I just bought my blower this summer and have only been able to use it a few times before the fuel line disintegrated. I call the customer support to try and get a replace part sent to me under warranty but was told it was due to the alcohol in the fuel. I don't feel that I should have to pay for the parts.
I will make sure to rate this item appropriately on Amazon and anywhere else I find this product.
