TBI injectors (just humor)

[Bob Valentine]

The colors are on the metal "fingers" that the inj connector latches onto.
 They're very often worn off, wiping the grease off them often takes the
color with it.  Think of them as the modern equivalent of chalk marks on
the frame of an old car....

I have two 4.3 TBI's here one from a van, one from a car.  Both have
yellow/blue, # 5235203 injectors  

Here's a repeat from the archives (the older one, gmecm.txt) :

Grn/Wht   305 CID eng  about 40 #/hr
Org/Blk   350 PU       about 55 #/hr
Yel/Brn   350 Cop Car  about 65 #/hr
Blu/Blk   Late BBC PU  about 80 #/hr
EarlyBBC PU  about 90 #/hr
