I would like to point out a possible gottcha on the
460 cc/min injectors. If you will note in the above list that the 86-87
460 cc/min low impedance injectors and the 88 13B NT 460 cc/min High impedance
injectors carry the same number 195500-1350. Therefore, you need to
insure that you use either the plug notch position or the color of the
connector (which may be hard to tell if old and dirty) is mentioned (or low or
high impedance) when ordering else you may not get what you
want.
I ordered some 460 cc/min injectors using that part
number thinking I would be getting the low impedance injectors and found out
the 460 high impedance had the same number.
FWIW
