ABSTRACT:
A pump module includes a fuel pump, a fuel filter having a filter casing and a filter element, a fuel outlet, and a pressure regulator. The filter casing covers at least a part of the outer circumference of the fuel pump, and accommodates the filter element. The fuel outlet is disposed outside the outer circumference of the filter casing, and includes an outflow passage for flowing the fuel from a discharge opening disposed on a sidewall of the outer circumference of the filter casing. The outflow passage includes a retrieve passage extending from the discharge opening to the sidewall of the outer circumference of the filter casing. The pressure regulator is disposed outside the outer circumference of the filter casing, and includes a regulator inlet for introducing the fuel, the regulator inlet being opened to the retrieve passage.
