    Uhhhh.
    Line one off timed port on drivereside front of carb to Vac Advance.
    Line 2 from port at base of carb front center to PCV.
    Line 3 from constant port on passenger side of carb near choke to the Thermac in Air cleaner.
    Line 4 Intake between carb and distributor goes up passenergside of fire wall and into cab for HVAC controls.
    Line 5 back of carb bas to Brake vacuum Booster.
    Line 6 (iff equiped) T off intake vac port where HVAC ties in to Cruise control.

    That's all the under hood lines it has.
