where is located the fuel filter on a 2006 Yukon xl 1500 5.3?

What is your question?

I bought the fuel filter in autozone but when got to the bottom of the SUV I don't see it any where. around the frame, nop around the tank, nop around the driver side (front and back) nop around the engine ,nop around the passenger side, nop I need help, the truck is working perfect, but I just don't want to wait until too late.
