Small hole bottom of Oil Pump

What we have here is a small very slow leak that is coming out of a small hole on the bottom of my oil pump on my 06 ZR750K or Z750S I believe same motors in each. Anyway anyone know about this hole and what its for? Should I plug it? replace the pump? rebuild it? Only leaks when it runs and it is very slow. If you don't know your oil pump its behind the water pump closer to the motor. Any help would be appreciated.

Thanks

Any chance for a photo?

Could be a bleed hole to prevent air lock after an oil change.

Thanks guys. I ordered the oil pump seal and the water pump seal and the O rings that separate the housings for the pumps. Getting great circulation with oil and the water as well and they are keeping very separated. I guess thats what the weep hole is for - so anything getting through from one towards the other leaks out. Like a warning. Slow going here should have it done in a month.

All The Best
