I recently put a AEM universal fuel regulator on my xp900 with K&T turbo. I first put the gauge right before the injectors and it was reading over 60psi of pressure which I know is way high. I moved the gauge to the port on regulator and it shows 0psi. The regulator is brand new. Maybe I got a defective one? I know the gauge works because I watched it go down when I was unscrewing it. When trying to adjust the pressure in both places it wouldnt go up or down.
