How to test fuel pressure ???

Hi, my car goes lean at high RPMs, and I've checked all of the basics. I'm left thinking this may be a fuel pump issue (I have two pumps, so twice the likelihood of failure, right?). Anyway, I went to AutoZone and borrowed this lovely Actron CP9920A Fuel Pressure Test Kit:



Problem is, I have no clue where the port is (if any) to read fuel pressure. I have an AMS fuel rail, dual walbros and a high flow filter. Is there a way to do this without completely breaking a fuel line open?

Thanks!
