Navien NCB-240E leak from air vent on circulation pump

I have a Navien NCB-240E combi boiler. It's leaking water from the circulation pump, pretty sure from the built in air vent. I can buy an entire circulation pump Navien 30015307A, but it looks like the air vent is removable. Possible to service this? I can't find the part for just the air vent.
