GM TBI Injector size, color and part numbers
TBI Injectors
If you have any other injectors numbers add them to the list.
xxxxxxx - color / color - 33pph - 2.8l and 3.1l
xxxxxxx - color / color - 45pph - 4.3l engine NOTE: Some came with 2 differant size injectors?
5235279 - White / Green - 54pph - 5.0L / 305 Cars/Trucks
5235206 - Orange / Black - 61pph - 5.7L / 350 Cars/Trucks
17084327 - Yellow / Brown - 65pph - 5.7L / 350 Police Package
17084304 - Black / Blue - 74pph - 7.4L / 454 - 91-93
5235231 - Red / Blue - 80pph - 7.4L / 454 - 88-90
17104288 - Pink / Purple - 46pph @13psi - 7.4L / 454 - 94-95 *NOTE: Came with 30 PSI regulator used @ 26-32psi for 67-72pph
These flow rates are a safe bet average @ 12-13psi, be aware that actual flow can vary by greater than 10% throughout production.

Re: GM Injector size, color and part numbers
This would be TBI, I would assume?
Re: GM Injector size, color and part numbers
yeah, those are all TBI... unfortunately, the MPFI/SFI injectors weren't color coded for easy identification...

all of the Delphi, and the 8 digit Rochester injectors should be GM injectors.... not sure of their applications though.
EDIT: well, the 12586554 is the 00-05 3100/3400 injector.
200cc/min at 3 BAR, yet they're run normally at 3.5 BAR

Re: GM Injector size, color and part numbers
Ive been looking for the flow rates for the TBI-700. These TBIs were used on the 2.0 and 2.2 GMs. Im running dual TBI-700s on a Chev Corvair controlled by a 6395 ECM, but guessed at the flow.
Thanks
