Can anyone help me identify the fourth inlet manifold vacuum pipe on my 2002 sportage?
There is 4 pipes connected to the inlet manifold.
1. Brake servo. 2. 4wd hubs. 3. Fuel pressure system. But I cannot see what/where the fourth hose is supposed to connect to. It is just below the foot brake servo pipe to the rear of the manifold. Currently it is plugged with a piece of wooden dowel as per the photo.
Any help greatly appreciated.
