Drain the Fuel Filter
During operation, the fuel filter on the engine will
separate water that may be in the fuel system.
This accumulated water can be drained from the
fuel filter by opening the small plastic valve, 1, on
the bottom of the filter, and draining fluid out until
clean fuel runs from the valve. Close the valve
and hand tighten only.
