Last week my son told me his blower was leaking gas when he used it. I told him I would get it next time I was there and see what was wrong with it. I got it over the weekend and looked for what I thought would be a broken fuel line. In fact the tank is cracked in the seem for about 2 inches. I found the crack this morning and removed the tank. I was able to easily slide a .003 feeler gauge in at one place. I was able to fix a craftsman gas tank once with a soldering iron but that was just a short stress crack. I found some new tanks but they are $25-30 plus shipping. I'll probably take one of my blowers to him and try to fix this tank. If it's going to leak I would rather it be in my out building than in his attached garage. I did a google search about cracked Hitachi blower tanks bit didn't come up with much, guess it's not a common thing.
