Let me beat this horse one more time just for the benefit of anyone that doesn't believe that you can't rely on the readings of a liquid-filled under-the-hood fuel pressure gauge. Here's a shot of my FE, iding at 870RPM as per the inductive tach, and the fuel pressure is showing just over 3lbs. -- but this is with the engine HOT. I know for a fact that my pressure is a healthy six pounds, and the fuel pressure gauge will read that when it is equalized. FWIW, my manifold vaccum is coming in about 13 inches, and that's what I use to tune my carb.
