Abstract: The present invention, in one form, is a fuel pump having increased pump inlet suction and outlet pressures as compared to known fuel pumps. Such pressure increases enable use of one fuel pump even with an engine including multiple cylinder banks, and facilitates elimination of vapor and air bubbles in the fuel. The fuel pump also does not include small, or narrow passages that are prone to be clogged by dirt or the like. More specifically, and in one embodiment, the fuel pump includes a pump housing including an inlet and an outlet. An inlet nozzle extends from the inlet, and -an outlet nozzle extends from the outlet. The inlet nozzle is configured to be coupled to a fuel line extending from a fuel tank, and the outlet nozzle is configured to be coupled to a fuel line extending to the engine block. The pump further includes first and second pump inlet covers. Each cover includes an air nozzle.
