I put a Holley "Red" pump on before I went to Piston and Paint. Engine ran great there and back. I was planning on putting a regulator on to make sure I'm not flooding the carbs. And because my heros BIG RIC and Bass have 'em. Here's my questions. Do I need a regulator with the Holley? The blurb on Speedway say "no regulator needed". Is it adjustable? Also, if the pump is putting out 7 PSI, and then splits to 2 carbs, doesn't the pressure reduce? Is there a way to determine how much, without running 2 guages? I just need to go really fast.
