A vehicle fuel pump module includes a jet pump assembly and feed tube that delivers fuel to the assembly. The module includes a jet pump choke that is disposed in the jet pump assembly and provides a reduction of pressure of fluid within the jet pump assembly. The jet pump choke includes include a choke housing that defines a passageway that extends between a fluid inlet and outlet, and a slot that is formed in a surface of the passageway. A ball is fixed within and obstructs the passageway, and abuts the slot. A fluid path defined between the ball and surfaces of the slot provides fluid communication between the fluid inlet and outlet of the choke housing.
