The purpose of the Fuel System Kit is to replace the components of the fuel system that are most likely to wear out, or collect dirt and contaminates, after prolonged use. Fuel system kits may include fuel pipes, grommets, connectors, clips, fuel filters, and other parts associated with your equipment's fuel system. Operating with a clean fuel system, including both the fuel filter and the parts that direct fuel into it, will improve the performance and prolong the life of your equipment.
