Disregaurd that lol it goes into the intake vacuum someplace. I wouldn't run it to the carb. You need to hook it to the tree.

If it helps you any I linked the Carb diagram from edelbrock in my original post which shows the vacuum lines.

You can hook it up there, that's essentially the same as hooking it to the manifold or the tree. For some reason I was thinking it should be timed vacuum but its not. So long as its a 3/8 vacuum to the intake.

Yes use the one on the carb, that the picture diagram lists for PCV.

Default Update!

Replaced the gas line that was cracked and leaking. Started it up and the pressure's fluctuating from 2-3lbs up and down. Tried to adjust the regulator by loosening the locknut and screwing the allen head bold but nothing changed in pressure... Seems like I might have a leak somewhere still, don't know why the pressure wont raise. Any ideas???


I also tried unplugging the 3/8 inch hose from the vacuum tree (the one going to the carb), and tee-ing it off so I could attach the PCV valve. So basically the PCV valve, and the Vacuum tree are both linked & attached to the PCV connection on the CARB. After starting it up with this configuration my brake booster didn't seem to be working right and it kind of sputtered when I hit the gas.


Still haven't been able to check timing but will this weekend.
