Does anyone know how the metal part of the vacuum line is suppose to rout. It is rubber from the TVS valve to the metal line with several bends and I would assume rubber piece again to connect to the EFE valve mounted to exhaust manifold. Does the metal line go over the driver side valve cover then down or come from around back of valve cover and to EFE. Does it go around back of the head and over the manifold heat shield. Just wondering if anyone knows.
