I'm connecting the vacuum lines for my carb swap, and the only line I have left is the one for the electric choke. Can I tee it into an existing line or does it have to have its own port? Here's how I ran the lines:

power brakes---PCV port on carb
PCV valve---vacuum port on intake manifold
vac. advance---vac. advance port on carb

Where should I run this line? Thanks.

 

I think that you have a couple of lines reversed. The power brakes should be connected to the intake manifold so that there is a good source of vacum all the time. The pcv should be connected to the carb. As for the choke there should be vacuum port quite close to where it mounts on the carb and the line is S shaped. It is the choke pull off. I am assuming that you have a qjet carb.

 

I agree with the comments about the lines you've connected.

I assumed you were talking about the Holley in your sig. If so, there is no such thing as a choke pull-off vacuum line.

 

Hmm, I guess I got the vacuum lines mixed up. Thanks, gmanuel, for pointing that out. I read in the TBI-->Carb tech article that the guy used the PCV port on his carb for his power brakes, so I ran the lines that way. After reading it a little more carefully, I can see he did that because he put a breather in place of the PCV valve. I'll route them the way you suggested.

This is for the Holley DP in my sig. I converted it to electric choke. That's why it now has the vacuum line. In the instructions that came with the choke, it says to tee it into any full manifold vacuum line. What would be an example of a full manufold vacuum line? Five7, thanks for your help with this and the spacer problem.

 

Full manifold vacuum can be tapped into the vacuum line for the power brakes
