Description of Change: A larger breather tube has been added to the fuel filling system in order to eliminate splash back of fuel and in order to improve the time needed to fill the fuel tank. There is now a kit available that allows the retrofit without drilling holes in the fuel tank.
Adaptable To: All the current machines with above serial break numbers above.
This retrofit can be accomplished with a (160-6934) Fuel Adapter Kit.
