    Help injector ident

    I have a bbc with a 94 throttle body. When I modded the engine I never took the injectors out, I upped the fuel pressure and did a tune and all has been well for a long time. Lately one injector started to not spray nicely so decided to pull them and have cleaned. When I pulled the injector that was working fine, it was something I hadn’t seen before and hope someone can identify. These injectors are the 94/95 bb injectors that run at 28-30 psi. The injector in question has a plastic top with no markings, a removable filter, vertical feed rather than side and up inside the shaft type end is 6 little holes that the fuel comes from.

    It's been maybe a year since I had them out, but they look just like what I remembered my injectors looking like from my 94 350.

    I think they were fed from the same place in the injector.
    That was a standard 12 psi system.
    They just look like tbi injectors to me.
    Maybe someone can chime in with differences between tbi injectors?

    FWIU 94-95 BBC injectors were smaller and ran at a higher pressure. Here's a chart from Eagle Mark

    I am guessing I didn’t do my question correctly. I know what the stock 95/94 injectors spec at and look like. When I took mine apart it had one stock gm injector in one side and the odd ball in question on the other side. It is the odd ball that I am trying to identify. Who makes it. It worked fine so my guess it is some kind of replacement for gm injectors.

    all the pictures show red insulation ( if that's what you call it ) on the electric leads.
    Yours are black?
    Maybe someone replaced it with the wrong one?

    After my last post I ran across an old post on a Camaro board and had pics of injectors that looked the same and came from a 305 in a camaro. They never did ident them and then the thread got off track. Mine had no numbers but one of the ones in the other thread had a partial 01B20(8) ??. I am wondering if they were out of some sort of a marine installation.

    Seems like I remember reading that they used the same injectors as low pressure 305 when they cranked the psi?
    If you look up 305 injectors, do they look the same?

    Any 305 injectors I have seen look the same as any other gm tbi injectors. Here is pics of the injectors on the camaro site

    I kept searching and the best I could come up with is an older standard motor products TJ11. The new smp tj11 looks more like a gm injector
