This is a great thread, and thanks to Scotty1998 and all y'all for adding to our collective wisdom.

I believe it was a white plastic piece just as you described. It definitely made a difference after I removed it. Its possible the replacement hose I put on was a smaller diameter and the "orifice" restricted it even further.
