Default Question about B20 w/ stock fuel rail and aftermarket FPR

I'm using an aftermarket fuel pressure regulator (one of the Ebay ones) with a stock B20 FI rail/loop for a Megasquirt install.

I don't seem to be able to get the pressure regulator to register any pressure on the gauge. I suspect that I just didn't install all of the lines in the correct spots. Anyone using a setup like this that can point me in the right direction?

Crude drawing for reference:

Remove the FPR from that location and install a "T" attach the T to both sides of that rail, and the 3rd leg to your feed. Use the port you have labeled as "fuel" to run to the FPR, and the outlet of the FPR as the return to the tank. Cap off the spot you have labeled as "return" or install a gauge there (thats the 5th injector spot).

Alternatively, you could just run a length of hose across the rail completing a hoop, if that makes sense, and use fuel as feed, and return to go to your fpr.
