摘要： An in-tank fuel supply unit is provided for supplying fuel from a fuel tank to an engine. The fuel supply unit generally comprises a fuel delivery module and a jet pump assembly selectively attachable to the fuel delivery module. The fuel delivery module has a housing defining a reservoir and includes a fuel pump for pressurizing fuel in the reservoir. The jet pump assembly has a suction tube defining a suction chamber and a nozzle situated inside the suction chamber. The nozzle receives pressurized fuel from the fuel pump and sprays the fuel from a nozzle tip at high velocity to draw additional fuel into the suction chamber through an inlet formed in the suction tube.

摘要： A fuel sender assembly comprises an electric fuel pump held in a mounting plate which is, in turn, mounted in a fuel tank, such as an automotive fuel tank. The mounting plate includes a chamber wall that defines a pump chamber having an inboard end and an outboard end. The electric fuel pump is received in the pump chamber such that an inlet end, which includes a fuel inlet, is disposed within the fuel tank adjacent the inboard end of the pump chamber. The outlet end of the fuel pump includes the electrical terminals and is disposed adjacent the outboard end of the pump chamber so that the electrical terminals are accessible outside the fuel pump for connection to an external power source. A hermetic seal is formed between the fuel pump and the chamber wall to prevent vapors from escaping through the pump chamber. The fuel sender assembly permits electrical connections to be made to the fuel pump without requiring wires within the fuel tank.
