Vacuum gauge source
I'm putting a vacuum gauge in the dash and I'm wondering where the best place to hook it up is - if I can avoid running the line into the engine compartment and instead hook it up in the cabin, that would be easier, but I'm not sure how that effects the accuracy of the gauge.

The closer to the carb the quicker it will react.
You can't connect it to anything that is connected to the vacuum tank and I believe all of the interior lines are connected to it. On the 72 and earlier even the heater control is taped into the line that runs the wiper door. Not sure where the later ones are sourced

Have to agree, if you want to know where your manifold vacuum is. you need to run a line threw the firewall to the manifold.
But why do you need a vacuum gauge in the dash.
I understand for tuning. But all the time?
