Gas Tank Valve

The ATV has a valve separate from the gas tank. There
are two positions: ON and OFF.
0739-082
In the OFF position, the valve will not allow gasoline
to flow to the carburetor. In the ON position (the nor-
mal operating position), gasoline is pumped from the
tank to the carburetor. The ignition switch must be in
the ON position to activate the electric fuel pump.
When turning the valve to either of the two positions,
be sure the indicator is pointed directly at the position
desired.
REMOVING/INSPECTING
1. Remove the gas hose from the valve by releasing
the spring clamp.
2. Remove the two screws securing the valve; then
