Its a Craftsman chainsaw model 358.356090. It's quite old but wasn't used much, and the plastic fuel lines are broken into several pieces. The Sears replacement kit is only about 4 bucks, so that's not a big problem. However, the exploded view showing the parts (http://www.ereplacementparts.com/craftsman-358356090-gas-chainsaw-parts-c-158286_172209_172243.html) shows only one plastic fuel line (item 18 in the diagram on that web site); whereas, the saw actually has two. It's crystal clear to me where the one attached to the fuel filter on one side and the carb on the other belongs, but I have no idea where the second one goes. I also don't know what it's function is. Some Craftsman chain saws have a primer which would account for a second line, but mine doesn't. When I removed the outside cover of the saw, the broken pieces of the fuel lines fell out. Each of the two lines penetrated the fuel tank, but I don't know where the second one goes to. I tried asking Sears via email, but so far have not gotten a response. Does anyone on this forum know the function of the second fuel line and where it goes after it comes out of the tank?
