I have a vacuum hose by the fuel filter that connects to the fuel pressure regulator and goes up to the top of the engine. I don't know where to connect this hose. This Vacuum hose is disconnected somewhere around the manifold?
I know that on 330i this hose is connected to the "F" pipe by the air intake tube, but 328i DOES NOT HAVE a "F" pipe on the intake tube.
Its #8 on the diagram, circled in red.
