Because on a carb'd motor the engine draws the fuel in itself and all the pump has to do is keep the float chamber supplied with fuel.Any excess amount of pressure will stick the needle valv in the chamber open and flood the carb/carbs!
With an efi the fuel is injected in by the electronic injector therefore has to be under pressure at the fuel rail hence electronic fuel injection!
