I have a line trimmer a Yard Machine 31cc and the fuel lines are dry and need to be replaced. I need a diagram of where each goes. There are two holes in the bottom of the tank and I am not sure what goes in that second hole. I broke the piece that goes in the tank and then come through to connect to the hose, so I need a new one of those. I was not sure how to put the hose on the piece that comes through the tank so it does not leak. Do you have a diagram.
