In-tank fuel supply unit

摘要

An in-tank fuel supply unit has a reservoir mounted on the floor of a fuel tank, and a fuel pump mounted in the reservoir. The fuel level in the reservoir is maintained by means of a jet pump which is supplied with fuel through a passage. The jet pump has a nozzle which directs a flow of fuel upwards into a venturi passage which has a converging section, a parallel section and a diverging section.
