Vacuum hose to no where

I would like to thank this board a lot of outstanding information I used so far. I have a 68 Riviera that I owned from 1970. The last time I used it was 19 years ago when I started it up and put it in drive and almost went through my neighbors front window. No brakes. So 19 years later I was smart enough to changed all the brakes, spark plug wires, points and oil. I didn't know enough when I started it up to prime the oil. I thought it was in the oil pan. Wrong. I correct that by taking off the oil sensor and pumped oil through it. It works great after all these years.

But my question is I have a vacuum hose coming out of the firewall and I don't know where it should be connected. I can't find an item that is missing a hose. Attach Is a photo. It's right below the relay left hand side. Two vacuum line one is connected to a canister and the other one is the problem. Thank you

 

no, its the vacuum line that is touching the two wires from the relay above

 

It looks like the hose that goes to the heater control valve?

 

Thank you Brian, I will check it out tomorrow. As I said earlier, the car was starting up great. Then I took the vacuum lines off the headlights to work on the canisters. I tried to start the car up today and it would crank but no spark. The vacuum lines wouldn't do that, would they?? Would it effect the vacuum advance on the distributor?

 

That line should run vac from the heater valve to the control inside the car.

 

I looked at the hoses for the heater and there is no valve. Where should it be

 

That line connects to the small heater/AC control vacuum tank which is hidden up above the main vacuum storage tank, under the left fender, (...p120-50 in shop manual) !
The hose connections are under the small vacuum tank just to make it more of a challenge when tracing, replacing or reconnecting them ? o No:
That line runs from the heater/AC control, and the other one runs down to the main vacuum distribution manifold on the lower firewall.

. . . get a '68 Buick Shop Manual, all the vacuum line info is in there + answers to questions you haven't even thought to ask yet !! :laugh:
It's the Bible for your car ! :TU:

 

Took your advice, just purchased bible. Thank you

 

Smart move !
Possibly the best investment you could make when it comes to maintaining your vintage '68 Riviera, or any other automobile !
I know you will find a lot of information in it ! :TU: :beer
