Fuel Filter Cup Cleaning
The fuel filter cup is a small well underneath the fuel valve. It helps to trap dirt and water that may
be in the fuel tank before it can enter the engine. To clean the fuel filter cup:
1. Turn the fuel valve to the “off” position.
2. Unscrew the fuel filter cup from the fuel valve using a wrench. Turn the valve toward you
to unscrew (see figure 16).
3. Clean the cup of all sediment using a rag or brush.
4. Reinstall the fuel filter cup.
