Fuel Rail Assembly - L61
The fuel rail assembly is mounted to the cylinder head and performs several functions. It positions the fuel injectors in the intake manifold, distributes fuel evenly to the fuel injectors, and dampens fuel pump pressure pulsations. Whenever performing any service on the fuel injectors, it is essential to re-attach the fuel injectors to the fuel rail (using injector retaining clip) prior to installing the injectors into the intake manifold.
