Sooo with my rebuild kit I have a couple of black pieces of rope. I'm doing my best to see where it goes(none came out of the pump when I tore it apart). Near as I can tell, according to my manual, it goes here. Sorry for the extreme close up, I wanted you to attempt to see what's in there now.
Edit: here is another pic. the area in the photo is under the black rope/packing. Check out my nifty bowl bushing.lol Sorry for the blury pic, f'n flash won't work..
