Our diaphragm-type air pump draws 80mA at 3VDC and has a 1/8" OD outlet. It's small and mounted on a small PC board (1-3/8" x 11/16" x 7/16" OA). Yours may or may not have 4" leads. If not, the positive wire goes to the longer of the motor leads. Comes with a self-adhesive strip on the side opposite the PC board. Originally designed to activate an equally small air-pressure switch.
