Abstract:
1. A fuel pump module for a fuel tank, comprising: a reservoir; an electric motor driven high pressure fuel pump having a fuel inlet and having a high pressure fuel outlet supplying high pressure fuel to an engine; a jet pump having a fuel inlet communicating with the fuel tank, a fuel outlet supplying fuel to the reservoir, and a jet nozzle of the jet pump having an outlet and an inlet connected through a conduit with the high pressure fuel outlet upstream of the engine for receiving high pressure fuel from the high pressure fuel pump for fuel flow through the inlet and outlet of the nozzle to entrain fuel through the inlet of the jet pump and discharge the entrained fuel through the outlet of the jet pump and into the reservoir; and at least one restrictor plate received in the conduit between and in fluid communication with the high pressure fuel pump and the inlet of the jet nozzle, the restrictor plate having an orifice upstream of the inlet of the jet nozzle and restricting the flow of high pressure fuel flowing from the high pressure fuel pump through the inlet of the jet nozzle.
