Just replaced the tubing on my saw (same model). Of the two stems coming off the primer bulb, the longer stem connects to a tube that goes to the gas tank. On the back of the tank there are two holes. The top hole has a tube that runs directly to the carb (overflow back to tank). The bottom hole is for the tube that goes to the primer bulb. There are notches in the housing for these two tubes from the tank to fit in so they don't get pinched when you put the two halfs back together. Don't forget to put the fuel strainer on the end of the tube in the gas tank. It helps hold it at the bottom of the tank. Hope this helps.
