This part is the fuel return tube for your outdoor power equipment. It is made of yellow plastic and measures 3x6x110mm. The return tube transports excess fuel back into the fuel tank after the primer bulb has been pressed and has primed the carburetor so the engine can start. Over time, this fuel tube can crack or clog, and this can cause problems for the engine. To replace this part, carefully pull the tube off the carburetor and the fuel tank, then connect the new tube. This part is sourced directly from the manufacturer and is an OEM part. It is sold individually.
