摘要： A fuel sender including a container in a fuel tank of a motor vehicle and, in the container, a filter, a fuel pump, a jet pump, and a pressure regulator. An upstream side of the filter and the fuel pump are connected through a first passage in a first end wall of the container. A downstream side of the filter is connected to an interior volume of the container through a convoluted second passage on a second end wall of the container. A pressure regulator on the second end wall of the container maintains fuel pressure at a substantially constant magnitude by variably restricting flow through the second passage. A venturi throat in the second passage aspirates fuel from the fuel tank into the container. The efficiency of the jet pump is maximized by minimizing the length of the convoluted second passage. Vibration isolating seals minimize the transfer of vibrations and pressure pulsations to the container. In a preferred embodiment, the filter has electrically conductive elements which are connected to a ground circuit of the motor vehicle for protection against static discharge.
