Assistance Needed
Could someone please identify this part and it's purpose. I could not find any info on it in my service manual. The round black ball with vacuum hoses coming out of it. Not the Duraspark module.
Thanks,
Thanks,

Thanks guys, is it specifically for the A/C unit? There was another vacuum reservoir that looks like a sideways can of coffee. Although that one was not able to hold vacuum due to corrosion. I removed it and capped ports for now. Is this going to cause issues later when I get the truck running? (rebuilding carb, now)

on my 79 f 150 400 w/AC and emissions. i deleted all of the reservoirs and coffee cans and charcoal boxes, everything emisions. and my AC still worked properly not sure if it is luck that it works properly. i have no 100% answer to say that it will work on yours. but it makes me feel better to have a cleaner engine bay.

The plastic ball is for the HVAC controls, having it will keep the air flow from reverting to the dash vents instead of floor or panel when, for example, flooring the engine to get up a steep incline.
The fruit juice can is used by engine-control solenoids (for the same reasons) and is depicted as VRESR on Vacuum Hose Routing Diagrams.

Thanks for the info, I looked in my service manuals under ac and it talks about vacuum leaks having effects on ac ventilation. I still could not find a complete vacuum line diagram for it. Yes, I remember Hi-C in a can. I remember Coke in steel cans. Anyway thanks again for the info. Side note PO gave me a 5 volume 1977 Ford Truck Shop manuals, in excellent shape.
Is Tang still sold in stores???
