pull off choke
« on: August 26, 2019, 07:50:37 AM »
4 barrel quadrajet. I have 2 pull offs. I need help with where does the vacuum line connect to from the pull off. The short 2" one is easy, I know that one but what about the other pull off

We would need the carburetor part number and application.  If it's stock someone may have a print of the vacuum hose routings if your factory decal is missing (usually is).....Cliff

The secondary pull-off is often vacuum sourced from the back of the baseplate beside the vacuum brake fitting.  If not you'll need to find someone who has a factory vacuum diagram routing to see where it comes from?.....Cliff
