I had an electric fuel pump looking like the one you show in the picture. It is a rotary vane and you cannot pump through it. It has been awhile since I have done this, but as I remember one way to check if your original mechanical diaphragm if moving enough. Take off the air cap (cannot recall the exact name) on top of the pump. Stick a small rod or screw driver in the hole. Turn the engine over and make sure the rod moves up and down about 1/4 inch or more.
