Rochester Quadrajet question

Post by g35me »

Can anyone tell me where to put these 4 vacuum lines on a Rochester quadrajet? Also I would assume that the large one in the front is for fuel, what type of fitting do I need?

also there is a vacuum line above the one that says "vent to charcoal canister" where does that one go? And if I have removed the charcoal canister what do I do with those vacuum lines? Where does the vaccum to the brake booster go?

Vaccum to the brake booster should come from the manifold not the carby..

Block the pcv if your manifold doesnt have the valve...it does nothing and is just pollution stuff.....Come to think of it my old holden v8 with a quaddy on it had lots of blocked pipes lol

top one to air cleaner i think . if your not using a cansister just block the ports. holdens & chevs run the booster into the manifold there will be a 3/8 threaded hole between the carby and distributor for a vacum fitting
