The link and the B are moved downward only by the diaphrabB The pump, therefore, delivers fuel to the carburetor only when the fuel pressure in the outlet line is less than the pressure maintained by the diaphragm springBndition arises when the carburetor float needle valve is not seated and the fuel passage from the pump into the carburetor float chamber is open. The fuel link is hinged to the rocker arm so that the link and the connected fuel diaphragm can be moved up, but not down, by the rocker arm. This pressure closes the inlet valve and forces fuel out through the outlet valve to the carburetor in an amount governed by the pressure in the pump-to-carburetor line. The return stroke (low point of cam) releases the compressed diaphragm spring which then exerts pressure on the B and the fuel in the chamber. Vacuum created in the fuel chamber by upward movement of diaphragm holds the outlet valve (M) closed and causes fuel to flow from the gasoline tank, through the inlet valve (not shown), into the fuel chamber. Movement of rocker arm is transmitted to the fuel link (E) which pulls the fuel diaphragm (I) upward from the fuel chamber (J) against pressure of the diaphragm spring (N). The arm is held in contact with the eccentric by the rocker arm spring (H).

The pump rocker arm (G) is actuated by an eccentric on engine camshaft.

The function of the fuel section of the pump is to draw gasoline from the tank and supply it to the carburetor in sufficient quantity to meet engine requirements at all speeds and loads. The bowl and screen should be cleaned periodically. The bowl provides a settling chamber for water and the dirt which cannot pass the screen. Fuel from the gasoline tank first enters the bowl then flows upward through the bowl then flows upward through the screen into the fuel pump.
