It is a standard squeeze bulb with two different sized fittings. It does not include a check valve to specify the direction of flow. Therefore, when trying to “pull” on a siphon, when one squeezes the bulb, one is also “pushing” the siphon back up the tube, unless you include other parts to prevent same.
