Product Description

This is a fuel return line, and it is used with various outdoor lawn equipment. Fuel travels through the return line into the carburetor, and from the primer bulb/pump into the fuel system. The line returns the extra fuel back into the tank. This part will crack and become brittle over time. If your fuel line is leaking, you will need to replace it. Before you begin repair work on your equipment make sure you drain the fuel from the tank, and remove the spark plug.
