I need a real quick answer... AFPR
It has been so long since I have done this I forget the proper way. I know I need to crank my fuel pressure up. I have the AFPR, but I forget how to do it properly. Can someone please give me precise instructions. Thanks my trans am is waiting.

It is a TPI system, isnt it? Just look under the back of the plenum where the regulator is. To increase the pressure, screw the screw in. To decrease it, back the screw out.

KF,
Connect the test gauge to the Schrader valve on the right (passenger) fuel rail. Start the engine and disconnect the vacuum line to the fuel pressure regulator. Monitor fuel pressure on the gauge while turning the adjstment screw on the regulator. The factory setting should be arount 47PSIG +/- 3PSIG. You may want to increase as much as 4-5 PSI even though you have the larger injectors. Your oxygen sensor readings at WOT will be your best indicator of correct pressure at full load.
Later,
Vader

Okay. Question for Vader. What tool exactly do you use to turn the screw while the test guage is still attached? I havent figured out how to do this yet. Pliers in no way work, and I have a wrench that works, but I cant get enough travel on it to move the screw while the test guage is attached.
I have to keep putting the thing on and removing it, and I'm uncomfortable with the amounts of gasoline I end up dripping on the intake manifold.
