Hi Evertone! I know this question is somewhere within the forums but I'm not smart enough to find it.
Anyhow, I just installed an BBK adjustable fuel pressure regulator for a bit more pressure. I have a gauge at a tee where the schrader valve use to be. Now (temporarily) I have a fuel pressure gauge and the line to my fuel solenoid. I followed the instructions from BBK to adjust the pressure; plugged the line from the manifod and adjusted the pressure to 42-43 psi like I wanted. When I started the car though, it was showing 58psi on the gauge. Where did I go wrong? Any help is most appreciated!! Thanks
