FG NA fuel rail bung
Replaces the stock regulator to allow the use of an external fuel regulator with the NA rail. The stock regulator is only rated at around 2.5 bar which means when running larger injectors and turbo the injectors will flow less then running the standard turbo pressure of 4 bar. Also when running high flow fuel pumps the factory regulator can struggle to bypass enough fuel to keep a stable fuel rail pressure and you can get over fueling at idle and lean conditions at higher loads.
Comes with the following
