An integral 1" paper fuel filter (4 cylinder system) or a 2" paper fuel filter (6 cylinder system) with check valve is mounted in the front of the float bowl behind the fuel inlet nut to give maximum filtration of incoming fuel. The check valve is used to shut off fuel flow to the carburetor and prevent fuel leaks if a vehicle roll-over should occur.
The float chamber is located adjacent to the primary and secondary bores. This feature assures adequate fuel supply to both carburetor bores during all normal vehicle maneuvers.
A single pontoon float, brass needle seat, and a rubber-tipped float valve with pull clip are used to control fuel level in the float chamber. The float chamber is internally vented through a vertical vent cavity in the air horn. Above this vent cavity is a removable vent stack assembly that has a small meshed screen at it's top portion. This vent stack provides the correct height for the internal vent.
The Varajet II float chamber also is externally vented through a tube in the air horn. A hose connects this tube directly to a vacuum operated vapor vent valve located in the vapor canister. When the engine is not running, the canister vapor vent valve is open allowing fuel vapors from the float chamber to pass into the canister where they are stored until normally purged. The venting of fuel vapors from the carburetor float bowl to the canister meets evaporative emission requirements and improves hot engine starting.
