Help finding primer bulb assembly for a maruyama bl8200 backpack blower

Found the bulb assembly online its ridiculously priced. Looking for one that will fit, anyone know a cross reference part?
here is a pic of what I've got, unfortunately the blower fell and broke the primer assembly off and I cant find it.

from the edge of the bulb it appears to be 24 mm from edge to edge.
