Holley 4000 Float Assembly

Tilt the main body slightly to keep the fuel inlet needle from falling out of its seat. Care­fully place the float assembly and float spring in the fuel bowl. To install the float and float spring in the main body, insert the long end of the float spring into the small hole in the float lever. Hold­ing the spring with the index finger, ease the float into the bowl and slip the spring over the boss at the bottom of the fuel bowl. Install the new float shaft and fit the fuel inlet needle clip over the float tab.
