No fuel pressure test port on 6.0L fuel rail,...Where is it?

[GSBZ2112]

I have to test my fuel pressure on my 2017 Silverado (with Service bed) 6.0L engine, and the Haynes Manual and even YouTube show the port on the rail on right side (passenger side). But i have no such port. I do see connectors to the lie got to< or should I say, coming from the tank, one at back of left side fuel rail, one just to the side of the trany at the frame and then one more at the tank. But I don't see a port anywhere on the line. How do I check fuel pressure for this vehicle?

Typically vehicles without a port require a temporary inline adapter that comes with the fuel pressure tester.
