My car has the deluxe heater, no A/C. The 61 shop manual Fig. 16-29 shows the vacuum source as the fuel pump. I installed new vacuum hoses following Fig. 16-29. My car also has the vacuum tank shown on Fig. 16-38 Standard Heater. This shows a tee in the distributor advance line with the vacuum source being the carburetor. The tee connectes to the t-stat on the heater box inside the car.
I was about to reinstall the vacuum tank on the fire wall, but could not figure out what connected to it. Looking back at the pics I took before disassembly, there was a vacuum hose coming thru the firewall connected to the vacuum tank. I have not started the car yet to see if the system will work as it connected. Which way is right, can I eliminate the vacuum tank on the firewall?
Thanks.

 

The vacuum tank on the firewall is keeps the vacuum working when you accelerate think of it as a storage tank you need to keep it

 

So, I need to route the vacuum source to the tank and then connect the outgoing line on the tank to the HVAC controls?

 

I think if we're talking about the same vacuum tank, it might be the one that feeds the power trunk release....

 

That makes sense. I have not reconnected the trunk release. There is only one vacuum source at the rear of the carburetor. The power brake booster gets it's vacuum here. I can put a tee in the line and run that over to the tank. The tank looks like a fat soup can. It is mounted on the firewall, to the left of the voltage regulator, just above the power brake booster.
Thanks.

 

Does anyone have a diagram for all the vacuum lines for '61 Starfire showing where they all should go? Thanks

 

I hope you have a Service Manual it should support your questions with the answers!
