In the center of the pump diaphragm is a brass (I think, could be steel) dimple, the top side is flat where the pump rod butts it, the bottom portion is an extension of about 1 mm or so.
It would be hard to alter the volume of the pump without changing the chamber size, the educated guess around here has been that the optional diaphragms have different length dimples, which have the affect of shortening or lengthening the accelerator pump stroke.
But as far as I know nobody around here has ever actually received one.
