Abstract
A pump module for mounting in a fuel tank of an automotive fuel supply system includes a housing, a fuel pump mounted in the housing, a pressure regulator conduit mounted in the housing, and a pressure regulator. The housing includes a module inlet and a module outlet in fluid communication with the module inlet. The fuel pump is in fluid communication with the module inlet. The pressure regulator conduit is in fluid communication with the fuel pump. The pressure regulator conduit includes a regulator inlet, regulator outlet, and a receptacle in fluid communication with the regulator inlet and the regulator outlet. The receptacle includes a first surface surrounding an axis, and a second surface surrounding the axis and the first surface to provide a void between the first surface and the second surface. The pressure regulator is mounted in the receptacle to selectively open fluid communication between the regulator inlet and the regulator outlet. The pressure regulator extends into the void between the first surface of the receptacle and the second surface of the receptacle. The pressure regulator includes a third surface surrounding the axis, and a fourth surface surrounding the axis and the third surface. A first seal engages the first surface of the receptacle and the third surface of the pressure regulator and a second seal engages the second surface of the receptacle and the fourth surface of the pressure regulator.
