225 V6 Vacuum Line Help

Hi there. I’m building my first 1968 Cj5 and I need some help on where the vacuum lines go. I have a port off the intake manifold, the vacuum advance, and the carburetor. Any reference photos on a complete 225 v6 would definitely help or just advice. Thank you!

 

On your first image, the small port on the front lower passenger side of the carb goes to the vac advance.

 

That’s what I had to begin with but there that other small port coming off the intake manifold so I wasn’t sure if I needed to connect that too or just plug it.

 

I have all 3 ports on the back of the intake manifold on mine plugged.

The small one goes to the heater and one goes to vacuum wipers I believe. mine has electric wipers. Not sure what the other one is for.

However, they are handy for connecting a vacuum gauge to though when trying to tune the engine.

My vacuum advance on the distributor is connected to the vacuum port on the carb as mentioned above.

 

If you have an original heater, the controls require vacuum and you will need one of those connections to operate the heater.

 

Perfect. Thank you everyone for your help! It truly means a lot.
