240z rack lube

Ok. here's some pics. The rebuilt steering rack (assumed reassembled with assembly lube) and shipped ungreased. Pics shows a zerk fitting below the steering shaft spline. Does the stock rack not have this zerk fitting in this location?

When gunning grease into the zerk fitting, How much is enough (original question) where should I see it ooze to know it's fully greased?

Re small bolt: read in the thread someone installed a second zerk fitting in the factory breather hole, passenger side. See pic. 

Sorry, not a ton of info in the FSM. 

Thanks, Andrew
