Fuel Filter - Kohler 4EOZ Service

5.3 Fuel Filter

The fuel filter prevents the entry of dirt into the fuel
system and preserves the injector and fuel injection
pump. The quality and condition of the fuel largely
determine the filter's useful life. Replace the fuel filter as
listed in the service schedule. See Figure 5-2.
