I know EXACTLY what your problem is. I have a new unit in my hand.. pulled the clip and then spent 15 minutes trying to get the clip back in! Its so stupid...ly simple. You need to come at the 2 slots, rotating the insertion by 90 degrees. You will never get it in by coming at it, the wrong location/angle. Also pay careful attention to the o ring gasket... if you PULL the 1 inch plastic piece out, 50percent chance the o ring will slide out and drop the ground (engine well!). You loose this your screwed.
