MG MGB Technical - test for rebuilt SU fuel pump

Is there a bench test one can perform on a my SU fuel pump which I have just rebuilt? e.g. If I apply power to the pump and while it is pumping if I close of the outlet ( as if the carbs were full) should the pump restart when you open the outlet port? Mine doesnt and this doesnt seam right. Please enlighten me.
Thanks in advance for your help. Brian

If it is pumping air and not fuel then blocking off the outlet or the inlet will change the speed of pumping (which will be very fast) but not stop it. If you are pumping fuel in your bench test then yes, it should stop when you block the outlet.
