Bypass regulator, Holley Dominator carb. Does it matter if you put the regulator before the fuel enters the carb on the fuel inlet or at the end of the fuel inlet after the fuel goes in the carb? Im replumbing my fuel system with a new electric fuel pump. I had the regulator at the end of the fuel inlet afters the carb. Because im mounting my fuel pump in the rear, it will be much easier and a cleaner install if i put the regulator between the pump and carb.
