70 psi fuel pressure??

[boxcarracer89]

My gauge has been reading 70 psi of fuel, so i figured the gauge was broken. So I changed out the gauge and made sure the new one read properly by air. That didnt work so I changed out my adj bbk fuel pressure regulator to an adj aeromotive. so the fuel pressure regulator and the gauge are both new. no matter how much I adj the regulator the fuel pressure stays constant at 70 psi? I have a new bbk 255lph fuel pump. but idk what the problem is any suggestions would be great!!

check the return line, it is probably pinched.

might be a vac issue if thats not it.

a dry nitrous kit will spike fp to 80 by vac alone
