    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.

    You need to add one to your chart....Its a marine application high pressure version of the 61 lb/hr injectors. Used on 400+ HP marine big blocks.

    25170301----Yellow/Black---61 pph @ 13 psi / 454/502 Marine *NOTE: Came with 30 PSI regulator used @ 26-32psi for ~100 lb/hr @ 30 psi

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

    I am guessing they are this part number?

    25170301

    Although they could just be normal 350 truck injectors. I ran a pair at up to 50 psi for thousands of miles. That was 20 psi base fuel pressure and a 4:1 rising rate regulator getting 7.5 psi of boost from under the Weiand 142. In about 1 year, I killed 3 well built 700r4s in about 20K with that setup.

    It looks like that's the correct number. I found a set on eBay: http://www.ebay.com/itm/Crusader-Mer...-/301647034737

    That's something I hadn't heard of before, thanks! I wonder why they went with the higher pressure and how much they flow?

    They run at higher pressure because they sit in a 454 TBI unit and feed 280-320 HP engines. Even the Marine 4.3s had a big block TBI on them making 210 hp.

    Just had some 5.0L/305 injectors PN# GM5235279*RPD cleaned and flow tested @22psi which yielded 72lbs/hr or 760cc/min.

    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

    I found info on these as I found these in my 1991 GMC Jimmy 5.7. The RIN-1001s are BWD Part number 57202P found here:

    http://www.oreillyauto.com/site/c/de...2521&ppt=C0024

    I can only assume since they are factory replacements for the "5235206 - Orange / Black - 61pph - 5.7L / 350 Cars/Trucks" they would flow about the same.

    I did have one question for the group, why did they use the 170301 injector in the 94-95 454 for street application, and why did they use the same injector in the marine 5.7? Anyone know why they used larger injectors in the marine TBI?

    Are there any benefits to using the higher pressure TBI injectors? Any internal design differences that allowed the injectors to handle the higher pressure?

    The later 454 uses higher pressure (around 30 PSIG) than the early 454 (around 12 PSIG), so it may actually be that they are using the smaller injector in the 454, rather than the other way around. From a quick search those are about 45 PPH at 12 PSIG, which would make them flow quite a bit more at higher pressure.
    The man who says something is impossible, is usually interrupted by the man doing it.

    The marine setups support and feed alot more powerful engines than the road going setups.

    One marine 350 I know of had L98/ZZ4 heads on it and was rated 315 HP with TBI feeding it. There was also a supercharged 502 that was around 600 HP and was dual TBI.

    I see conflicting data on the 5235206 Orange/Black. The truck 5.7 injectors, I am seeing fuel rates at 55 pph versus this forums listing of 61 pph. Is there an error.
