Abstract
A carburetor includes a body with an air intake path, a fuel pump and a fuel pressure regulator. The fuel pump and fuel pressure regulator are positioned on the same side of the body. A fuel pump and metering chamber diaphragm is sandwiched between the body of the carburetor and a pump body and cover. The diaphragm separates a pump chamber from a pulse chamber of the fuel pump and separates a fuel chamber from an air chamber in the fuel pressure regulator. Inlet and outlet flapper valves are part of the diaphragm or a separate flapper valve member positioned between the body and the diaphragm.
