    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.

    This would be TBI, I would assume?

    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

    What about the injectors found in the 2.5L Iron Duke TBIs (single barrel)? I can't seem to find their specs anywhere. I'm using one to inject an Opel 1.9L.

    Hello everybody!
    I just got myself an injector Delphi FJ10041-11B1. But when I opened the box, I saw that the number on injector itself is "5817", and number on injector on my car is "5227". Could someone tell me the difference and provide flow rate for "5817" injector? Flow rate for "5227" is 50 lb/hr at 12 PSI.

    Regards,

    Milos

    Do you have a part number for those injectors? I'm assuming that they're not '206s.
