Aeromotive FPR, fuel pressure doesnt change if vac removed

I have a pretty new Aeromotive FPR, and for some reason when you pull the vacuum line off of the nipple the pressure wont change while the engine is running. The nipple is supposed to have a vacuum line hooked to it, and the FPR draws a vac source from the LIM near the cold start assist as per emissions removal instructions. Why is this? will it hurt the car when it gets on boost?

Is your vac line actually sucking at idle?

Im measuring the fuel pressure with a gauge inserted into the front of the FPR. And the line that the fuel pressure regulator is getting its air from pulls 16 psi of vac at idle.
