    vacuum lines

    Hello, I cant find info in the green bible on vacuum lines. Can anyone help? I have the following vacuum ports, can you tell me where they connect? (my engine came dissassembled):

    Dist. vac advance.

    Oil cap.

    Small port on intake air elbow to carb.

    Small vac port on carburettor. (I assume this goes to the distributor)

    Large vac port on carburettor.

    Small vac port on breather tube.

    Thanks a ton!

    I am not looking at my truck, but going off memory I believe the following:

    Dist. Vac. Advance runs to your carb.

    Oil Cap Breather runs to the Elbow you refer to.

    Large Vac on Carb would run to your Servo.

    The other scenarios you describe are the same thing posted above.

    Hope this helps (and I hope it's right).
