The engine has Edelbrock heads with no crossover. We do have ethanol in the fuel, the pump sticker states "Up to 10% Ethanol."


I used the infrared thermometer to see what temps I was getting.
Just idling in my 75 degree shop, engine at 195-200, the carb primary bowl was at 135, the fuel line was between 110 to 140. Fuel pressure started to drop to 4, the filter started to empty out a little. I went for a drive, 20-30 minutes or so. When I got on the throttle, it ran great then started to drop off as I went to 2nd gear. This is probably where I am running out of fuel. Back at home, I checked temps again. The fuel line had jumped to the mid 160s, the carb primary bowl was at 135-140. The filter was at 125.
I prefer to know why something is failing rather than to just replace it. I'm sure an electric pump, regulator and return line would solve this.
