--------------------------------------------------------------------------------
look at the how-to that's posted...
Your pics don't work
Another reason I don't like chilton manuals...
CPI=Central Port Injection...92-95 4.3 motors
CSFI=Central Sequential Fuel Injection 96-2000
CMFI=Central Multiport Fuel Injection-2000-2004 Standard, 96-1999 if you had injection problems (clogged, stuck open) and had the system upgraded. This was actually a recall issue for california I believe.
This is a CPI motor and CPI unit.. See thread here for more pictures...

CSFI
CMFI
(Note, the CMFI above is the 8 cylinder version, no diff in the 6 really except less 2 nozzles) CMFI will work in CSFI motors w/ the conversion kit
