Got a small issue...72 442 with a 350.

Ive located two vac lines that come thru about the middle of the firewall with some wiring and into the engine bay. One is a larger diameter one and the other very small diameter.

Cant recall what they are for and the Service maunal didnt help.

Can anyone assist?

 

One main vacuum line for the A/C controls and another hose (with white stripe if original) for the heater valve.

 

A/C controls and hot water valve.

edit: Damn you're fast, Rob.

 

Thanks fellas!
