when using a adjustable fuel pressure regulator such as the direct fit nismo unit, where do you install the fuel pressure gauge?

it doesnt make sense if you install the gauge between the fpr and filter since it would read the same fuel pressure no matter how much u adjust the fpr, since the fuel wouldnt even reach the regulator at that point...

i would assume u have to install it after the fpr but i dont know where or how, especially on a stock fuel rail

p.s. i searched but i didnt get a definitive answer

You want to put it between your fuel filter and your fuel rail.

No, it doesnt have a constant pressure. The FPR automatically opens and closes some to regulate the pressure 'behind' it(in the rail, and the whole line from the fuel pump to the rail).
