1998 SVT (and I assume ST200) used LIM with 32mm secondaries (compared to non SVT 31mm)
1999/2000 SVT uses LIM with 34mm secondaries which is a modified version of the 99 3L (same 34mm butterflies). Some 99+ non SVts (several Cougars) have been found to have the 34mm as well. Some say if you have the returnless fuel system only HOWEVER, I have a 99 with return style and have the 34mm...
2000+ 3L use "oval port" lower, completely different with no butteflies.
