A 'bypassing' fuel regulator has a return line that carries the fuel back to the tank that's not needed by the carburetor. That maintains a flow of cool fuel, whereas a 'blocking' type regulator holds that fuel and releases to the carburetor only what it needs. By holding the fuel it provides greater time for the fuel to heat up.
