I've done some searching, and I know that our cars came with 2 different size injectors. What I don't know is how to tell the difference? Is there a different coloring or PN on the bigger inejctors?

Thanks!

 

1994-1997 fuel injector - PN 17124248

Not sure what the PN is for the 93's.

 

Thanks very much.

 

The '93's use PN 17105094, in case anyone's interested.

 

just to update the thread a little bit for future searchers. When Injuneer gave me a PN for the injectors, I looked at mine a little closer and found a PN etched around the top of the black portion of the injector. I was used to Bosch style, so hadn't noticed the PN before.

Unfortunately the PN was close to the one give for the 93 injector, and I worried a bit that I actually had the smaller injectors. However a few minutes with google and I found that the injector PN 17095004 is also a 260cc 24lb injector. So it looks like there is at least one more injector PN for 24lb LT1 injectors.

This website, where I found info on my injectors, looks to have a pretty good collection of flow data on some common GM injectors.
