This is incorrect because the gauge is connected at the outport here. The gauge should be connected between the pump and the FPR. It is connected after the FPR on the picture. It will show a return line pressure, if there is any tangible. It will not give fuel rail pressure.

I put in a tee fitting temporarily just before the fuel rail.
I have to do this again this weekend because I've had to have the car towed home twice this week.
I may be having issues with a dying fuel pump.
