FUEL SUPPLY DEVICE

摘要

A fuel supply device is achieved which can have a more compact fuel pump said fuel supply device having a configuration in which some of the fuel which has been pumped to the outside by driving of the fuel pump can be returned to a housing unit where no fuel pump is arranged. A jet pump (68) is provided in a vapor discharge tube (64) capable of returning fuel from a fuel pump main body (42) to a second fuel housing unit (38S). The cross sectional area of the flow path of the vapor discharge tube (64) can be changed by a float valve (76).
