ABSTRACT:
A metering fuel pump adapted for feeding fuel containing vapor or air to an engine that includes a housing assembly. The metering fuel pump further includes a motor section encased inside the housing assembly for providing the required rotary motion to a two-stage pump section. The speed of the motor section is controlled by a motor controller section that provides a voltage regulated flow of fuel. The two-stage pump section imparts pressure to the fuel and encloses a cyclonic vapor separator section.
