Does anyone have the diagram of where the 3 heat and a/c vaccum hoses under the hood hook up and how to tell which is which,1969 Dart. TIA
yes i think they are.mine has 3 vacuum lines coming thru firewall,1 to vacuum cannister and it goes to engine and then
2 to heater water valve
Thank you for the help.That was what i neededThats how my car is. The solid black hose is vacuum supply. And the black/red stripe and black/white stripe go to the valve. Currently my valve will open but it won't shut by itself. There isn't any vacuum supply to it.
