chaos on Friday again.. forgot my book. if you have a manual look at the Canadian drawing and that's the minimum you probably want to run. things I'd run brake booster, PVC, distributor. vacuum to the app, choke opener and idle up valve for deceleration. if you have a vacuum switch I'd run that too because it idle shut down solenoid. i replaced all the hose's on my rig and nothing worked. then i discovered that the screw in vacuum hose conection in the middle of the manifold was loose. good luck.
