Hi-
I found another bolt with spring inside at Pic-n-Pull and installed it after making sure the spring length was correct. Drives rather poorly with the new 'spring/bearing-loaded bolt' mainly due to the fact that the IP is now leaking (drawing air) at the input fuel connection- it did not leak before this. Good idea to check fuel pressure (will do) but I'm assuming my Fuel Pump seems to be motivating the fuel with plenty of pressure as it gets 'tickled' by the IP.
Thanks for the insight!
