Vacuum Hose help
Hey guys. Working on my '72 'Burb, with front and rear AC.
Got a vacuum hose that isn't hooked up to anything, and I'm not sure where it is supposed to be hooked up to. See the picture. The hose with the red arrow goes to the vac ball/tank assembly on the other side of the housing, close to the engine/air cleaner. The hose with the green arrow loops to the actuator thing (where the arrow is pointing). The hose with the yellow arrow doesn't hook to anything. Any ideas as to what it is supposed to be hooked up to?

Re: Vacuum Hose help
Okay, I actually got this wrong in my picture. The red hose does NOT go to the vac ball. It goes through a grommet on the firewall.

Re: Vacuum Hose help
hard to see with that pic. could it be the windshield washer fluid to spray hose(s). the line through the fire wall probably hooks up to the washer pump mounted inside.

Re: Vacuum Hose help
No, my washer pump and related hoses are on the driver side. This is on the passenger side, around all the A/C stuff.

Re: Vacuum Hose help
I just added factory Four Seasons Air to my 70 Burb. On mine, the Vac hose from the tank came through the firewall and attached to the passenger side nipple of the vacuum valve on the controls. A vacuum hose went from the drivers side nipple of the control valve to a Tee which with one branch going back through the firewall to the cowl vent actuator for the air shutoff valve and the other going to the recirculating valve actuator for the kick panel vent. Not sure how the setup changes with front and rear air.
