I was replacing a few vacuum hoses on my car and found a couple that dont connect to anything and im pretty sure thats not a good thing. Does anyone have a engine compartment diagram to show where these things go! Its a 1979 280e euro. The two that are disconnected are on the left side of the engine and run around the back of the engine and are cut. Ayn help would be greatly appreciated. I was hoping to have the car up for sale already but My wife and I are expecting another baby possibly today... and things have been slightly hectic!
