Claim Text:
1. A fuel pump module which supplies fuel to an internal-combustion engine from a fuel tank having a plurality of fuel tank rooms and discharges the fuel from the fuel tank to a combustion chamber of the internal-combustion engine, the fuel pump module comprising: a first pump discharging the fuel from the fuel tank to the combustion chamber of the internal-combustion engine; a first filter removing foreign substance from the fuel that is discharged from the first pump; a first supply port disposed at a position between the first filter and the combustion chamber into which the fuel is discharged from the first pump, the first supply port allowing the fuel filtered by the first filter to flow therethrough; a second pump discharging the fuel from the fuel tank to an air-intake system of the internal-combustion engine; a second supply port disposed at a position between a second filter and the air-intake system, the second supply port allowing the fuel filtered by the second filter to flow therethrough; a jet pump transporting the fuel to a first fuel tank room that houses the first pump and the second pump from a second fuel tank room; a communication passage providing fluid communication between the first fuel tank room and the second fuel tank room through which the fuel transported by the jet pump flows, wherein the jet pump causes a swirling flow of the fuel when the first pump or the second pump discharges the fuel; a filter case housing at least the second filter; and a subtank connected to the filter case at a position that is lower than the filter case, wherein the jet pump is disposed at a position between the filter case and the subtank.
