A fuel pump module supports a port injection (PI) fuel pump and a direct injection (DI) fuel pump by utilizing a combination structure of a pump case for housing the PI fuel pump and an other pump case for housing the DI pump case. The two pump cases are combined via a support part. The support part includes an outer wall of a cylinder part of the pump case which extends outwardly toward a radially-outer portion thereof. The cylinder part houses the PI fuel pump. The support part has a C-shape, and supports the other pump case which houses the DI fuel pump, a DI filter and the like. As a result, the fuel pump module has a fewer number of parts and a reduced volume.
