A fuel supply device for an engine has a pump module comprising a fuel pump and a fuel filter. The pump module is housed within a sub-tank mounted in a fuel tank. The fuel filter is shaped arcuately in section and fitted around the outer circular periphery of the fuel pump. The sub-tank has a concave space on its outer periphery. The concave space and its above space accommodate therein a part of electrical connector, a fuel level gauge, electrical lead wires for the electrical connector and the fuel level gauge, a jet pump and a connecting pipe for the jet pump and a fuel return port. This arrangement reduces the diameter of the fuel supply device and facilitates mounting work of the fuel supply device in a limited space in the fuel tank.
