Default stock injectors on a 5.3

I have an 02 Yukon 5.3 liter 2WD. Can anyone tell me what size my stock injectors are?

If its a standard fuel system, the injectors are around 24.6 pounds. If you have the flex fuel system, I'm not sure.

Theres no need to change the injector with just a few bolt ons. Heads and cam, dry nitrous or forced induction may require larger injectors.
