    Quadrajet Vacuum Hoses for 72 Chevy

     



    I have a 72 chevy with a quadrajet - tried to determine if the vacuum hoses are hooked correctly. Does anyone have a vacuum hose diagram? What connection on the carberator goes to the vacuum advance on distributor. Would appreciate any help. Thanks!

    A Haynes manual will have what you need....With the engine running find a port that has vacuum at an idle....Usually by the chock pull off will be the one you want....this goes to the vacuum advance.... there is one that is bigger and generates vacuum as you rev the engine....this goes to the egr valve....
