    Can anyone tell me the difference between these two injectors r-3411753, 4902921. Got a ism with a bad injector 4902921 and I have a fresh 6 pack for a m11 r-3411753. Any help would be appreciated.

    Those engines are on both sides of a big cam. If they fit in the hole you will not be happy.

    Understood... it was worth a try though. I know you have a lot of literature with parts numbers.
