in the link i attached one guy said that the tempo, topaz and old taurus 4 cyl single bbl TBI's are direct bolt on if u can bolt on a carter YF(A) 1bbl...so if u only want to do 1 TBI in place of the carb, then it should bolt on..then u just have to worry about the computer and the fuel return line...i would get the fuel return line done at a shop, and DONT weld it.

with the programmable modules, do u buy a disk or something that allows u to tune up the module?


got my 78 merc with a 250 I6 and i love it.
