GM LS3 fuel rail kit for upgrading the fuel system on FAB GM LS engines. The fuel rail kit is used to distribute fuel to the injectors and is suitable for tuning, turbo and motorsport projects where a more flexible and upgraded fuel setup is required. The kit fits FAB LS3 manifolds.
This fuel rail solution is relevant when fitting larger injectors, an upgraded fuel pump, an external fuel pressure regulator or a modified fuel system. The fuel rails can be integrated into an AN-based fuel system with hoses, fittings and regulator according to your own setup.
