I have 1998 Porsche 993 and I have found a vacuum hose disconnected and was hoping someone could advise me where the other end goes. I have attached a picture I found on a different forum that is a good picture to see what I am asking but is not my car and disregard the red arrow as it has no bearing on my question. I need to know where the other end of the vacuum hose goes that in the picture comes straight out the bottom of air injection control valve that has the electrical connector on top. In the picture it appears to head toward the front of the car in a solid plastic air line.
Can anyone out there help me?
