I'm having problems with too high of fuel pressure. I've purchased 2 different Y-block fuel pumps and one FE fuel pump. They all put out 7.5 to 8.5  psi which was causing the Holley carb to flood the engine. To try to correct the problem I've tried 3 different fuel pressure regulators which don't work. The last one was just installed a week ago and already went bad.  Unable to adjust (pressure drifts).  Anyone else having similar problem and what does it take to correct?  Dave V
