String Trimmers

I purchased a Husky 122c string trimmer in the spring of 2011 and have used more or less weekly since then. In the summer of 2012 the gas tank developed a leak that created a hazard as you might imagine! I had a new gas tank installed and within one hour the NEW tank started gushing gas down my arm. My gasoline contains an ethanol fuel treatment. Is there a manufacture flaw in the 122c gas tanks? How can this problem be resolved. Of course the trimmer is out of warranty!

Thanks
