A fuel pressure regulator is installed replacing the factory one which is mounted on the fuel filter. Due to this, modification to the fuel line is necessary. The fuel return line is brought up to the engine bay. The pressure level is regulated from the manifold pressure taken from the crankcase valve port since it was removed. And the valvetronic is disabled on this car means that it is using butterfly valve to regulate air intake.
