Injector flow number location on AC Delco reman?

Hi all,
I replaced all of my injectors over the weekend. #7 is setting the code for incorrect injector flow rate number.

Does anyone know for sure if the number is also located anywhere on the injector body itself? I do know that they cross out the numbers on the top they originally have when they rebuild them.

These are GM/AC Delco remans. I need to verify that number against the number on the package if possible!

I have searched on here and the web with no luck, thanks in advance if you can assist!

I don’t think there is a ACDelco injector. Maybe GM/ACDelco part number.
97780360 INJECTOR, Fuel Injection
INJECTOR,FUEL(INCLUDES 12,293,378)(REMANUFACTURED-NOT FOR SALE WHERE IMPORTS ARE RESTRICTED)
You sure there not OEM Bosch injectors?
Maybe [email protected] will chime in.
The Bosch remans the flow rates echted in the side of the injector body. But you will also get the sticker.
You get a sheet or card with the new/rebuilt injector that has a flow number on it
What is your code DTC P160C?

These are Bosch remans one would purchase through a GM dealer. The flow code is on the foil package they come in. If the number is indeed etched on the side I can pull it and compare to the package.

I have reset the codes and only had an issue with this one. For giggles I put the original code in for that cylinder and it doesn't set a code but I know the code is wrong. Put the new code in again and the code is back.

From what I see on the the AC/Delco Remans, the numbers are on the side of the units next to the connector:

I saw those numbers on the connector, they do not jive with the flow rate code. I think I need to pull it out and look on the body. Thank you everyone.

Try contacting a local auto parts store and see if they have one on the shelf they can pull and locate the code

Update from last night for closure. I pulled #4 injector as it is only a 15 minute or so deal.

The GM/AC Delco Bosch reman. injectors do indeed have the flow code inked on the side of the black top connector. Very small, hard to see for sure.

I reinstalled #4 and was able to use a bore camera to verify the numbers on #7 which was setting the code. The flow number matched the package.

Now what? I reset the flow code for #7 and the code still set. Verified my numbers again, changed it back to the original flow number, cleared codes and back to the new number and the code did not reset. Pretty sure I made an error somewhere but all is happy now it seems.

I will write up my P0087 story at some point in the near future. Thank you to those whom chimed in
