13. Reconnect the appropriate vacuum hoses noting the correct fitting from Figures 1,3, and 4.
A. Plug any vacuum source not used.
B. The “timed spark” fitting does not provide vacuum for distributor advance at idle. Vacuum for advance is available as soon as the
throttle is opened from idle and the engine is placed under a load, such as acceleration or cruise. If in doubt as to the operation of this
vacuum source, connect a vacuum gauge to the fitting and drive the vehicle noting the various vacuum readings.

14. The fuel line will have to be cut and connected to he carburetor using a “dual-feed” fuel line, such as Holley P/N 34-150. See Figure 5.
When cutting the fuel line, use a tube cutter to provide a clean cut.
WARNING: In all cases where the fuel line has been cut, it is essential that it be clean to insure that no metal particles enter the fuel bowl after
the new carburetor installation. This is performed by disconnecting the fuel line at the pump and blowing the line clean with
compressed air. Holley DOES NOT recommend the procedure where the coil wire is disconnected, the engine is cranked for a
few revolutions, and the fuel is collected in a container. This procedure is unsafe, because sparking can occur either at the coil, or
at the distributor end of the coil wire, and then ignite any fuel spilled in the engine compartment.
