OPERATION

The Fuel Filler Cap incorporates a two-way relief valve that is closed to atmosphere during normal operating conditions. The relief valve is calibrated to open when a predetermined pressure or vacuum occurs in the fuel tank. When the pressure or vacuum is relieved, the valve returns to the normally closed position.

WARNING: REMOVE THE FUEL FILLER CAP IN ORDER TO RELEASE FUEL TANK PRESSURE BEFORE DISCONNECTING ANY FUEL SYSTEM COMPONENT.
