Change the whole injector and then go the extra mile while you have it apart and replace the O rings on the other 7. This way next time you'll know it's the injector.

Is the fuel leaking out into the engine bay or onto the intake manifold? If so it is likely a bad oring (assuming the fuel rails aren't damaged and weren't knocked around or anything like that). If it were me, I'd get a set of orings and replace them all.

The fuel is at the base of the injector and is filling in the small crevice of the intake

Sounds like it is leaking from the top, you can just try replacing the o-ring. Autozone sells them seperately.

Sounds like o-ring to me too.
Try GM part# 12482706. That's the set. Inexpensive too; especially when you get them through one of the GM dealer forum vendors here (there are three).
