Yeah it's driving me crazy too. I have FP regulated at 6.5 psi and am using a Carter mechanical strip pump with regulator. 3/8" pickup and line to the front. I will be adding the in-car fp gauge next week. The pump is the only thing different from 20 years ago. I think I had two holley blue pumps and a fram filter back then. Now mechanical pump. I also checked the vent tube on the tank to ensure it wasn't plugged.
