NOTE: With the engine turned off, have an assistant slowly press the accelerator pedal to the floor, while you watch the
throttle for any sticking or binding. Correct any sticking or binding conditions before proceeding. Also ensure that you
are reaching full throttle. Many performance problems are traced to partial throttle openings from improperly adjusted
linkage.

6. Reconnect the appropriate vacuum hoses to the carburetor, noting the correct fitting from Figure 6 and 7.
A. The full manifold vacuum source in the front of the throttle body provides vacuum for proper operation of the air
cleaner, the pump diverter valve (if equipped), AC/Cruise, and/or the temperature sensing valve. If vacuum for more
than one component is needed, use small plastic vacuum “T”s (available at most automotive stores).
B. The timed spark fitting in the front right corner of the throttle body provides vacuum for the operation of the distributor
vacuum advance. Connect the hose to the distributor, spark delay valve, and/or temperature sensing valve as
originally connected. Again use “T”s as necessary. If any questions arise about the hose connections, consult the
proper service manual.
7. Connect the PCV hose to the PCV fitting in the carburetor.
8. Connect the power brake hose to the fitting as shown in Figure 7.
9. Install a fuel line of the correct size (Holley® P/N 34-150).
