ABSTRACT:
A multiple pump fuel delivery system is provided, which in one preferred embodiment includes a tank. Mounted within the tank are multiple fuel pumps. The fuel pumps have intakes connected to filters. One pump may be connected to a fuel only passing filter, and another pump may be connected with a fuel-water mixture passing filter. Fuel from the outlets of the pumps is delivered past non-return check valves through a manifold. The manifold is connected with a pressure regulator valve, which is fluidly communicative with the engine of the vehicle. A relief outlet is also provided to return excess fuel.
