Default How to tell if the injectors I bought are 28/26

I bought some 28lb injectors and was wondering if their is a PN I can check to make sure they aren't the 26's I am replacing.

Thanks

What part numbers do you have on the sides of the 28lbs injectors you have? Tell us some numbers, or see if they are the same numbers as your 26lbs. I will look at my old 26lbs. and tell you the numbers in a second. This guy on here named Badmire sold me some so called 28lbs injectors until I checked the numbers on the sides of them after they arrived with my Ls1 performance book and they were 26lbs.
