Abstract
An apparatus and method are provided for a fuel bowl to supply liquid fuel to a carburetor. The fuel bowl comprises a float chamber and a fuel inlet cavity which receives a fuel delivery insert. The fuel delivery insert receives a fuel inlet valve and comprises passages to direct incoming fuel to a bottom portion of the float chamber. A float comprises an elongate member rotatably hinged within a float cavity of the fuel delivery insert, such that the float rises according to a quantity of fuel within the float chamber. The fuel inlet valve supplies liquid fuel to the float chamber by way of the passages according to the operation of the float within the float chamber. A ventilation chamber allows air and fuel vapors to exit as liquid fuel enters the float chamber while preventing liquid fuel from entering into the carburetor.
