Ahhhh OK I thought it must have gone gone to the rail underneath where you can't see. Yeah like I said there was a few changes over the years with very similar engines. I know @gtrboyy had a VP with a V6 he might have a better idea being closer to VN Buick than my bus.I thought fuel line was just around the manifold that fed the injectors. But emission control system maybe????
The short hose that does a 90° bend is the PCV valve breather pipe return to the intake manifold. The black steel hard line is the coolant bleed line. On the LS motors they call em steam vent pipes. Basically these lines come from the highest point on the engine and bleed out any air that may be in the system. On an old motor it pays to remove and make sure they aren't blocked for optimum operation.[/QUOTE
