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 (Fig. 13).
2. Unscrew the fuel filter cup from the fuel valve using a wrench. Turn the valve towards you and unscrew it.
3. Clean the cup of all sediments using a rag or brush.
4. Reinstall the fuel filter cup.
