A manually operated fuel control valve having at least two operating positions, one being an "on" position for feeding fuel through a main fuel inlet when the fuel tank is full and the other a "reserve" position for feeding fuel through a reserve fuel inlet when the fuel tank is nearly depleted. The valve includes a valve closure means which is disposed in a partial sealing relation with the reserve inlet when fuel is being fed through the main inlet. The fuel valve also includes a shear zone to cause the valve to break away from the fuel tank in the event of an accident. The internal parts of the valve are biased toward a valve closing position to immediately shift and completely close the valve against further flow of fuel upon breaking of the valve.
