OK, just stuck the camera down behind the engine and pointed it where the EGR tube went. How the heck anyone can get in there and chaange the valve is beyound me. But here' the pick of where the tube goes....sorry about it being a little fuzzy.
Pat Blue Cruiser. By you picture, your right about not having the tube that connects to the back of the manifold, but as SuGammer said, all the engines need one. Maybe from the EGR valve down at the bottom (see my latest Pic) the valve is connected somewhere else on the engine or manifold. [:I]
