I've not seen a Command with three vent holes in the fill cap.
As stated above, the fuel pump works off crank case pulses. As the pistons go up/down, pressure rises and falls in the crankcase and pulses the diaphragm in the pump. I don't see how the pump could work with a vented fill cap or even the crank case breather.
I could be all wet but don't think so.
