I have a 1985 Monte Carlo 4.3 liter. I can't figure out where two vacuum lines run to. I have pics of both if anyone could leave their email or allow me to send them the pics for some direction it would be greatly appreciated.

 

one is right by the coolant tubes to the heater core the other is behind the air filter if that helps.
