PROBLEM TO BE SOLVED: To provide a vehicular fuel supply device capable of enhancing the mountability of a fuel pump and a filter on a vehicle and easily connecting a fuel pipe, and suitable for a two-wheeler. SOLUTION: In a fuel pump module unit G, a fuel flow-in chamber 6 with a fuel suction passage 9 being opened is formed below a pump accommodation chamber 3, a pump suction passage of a fuel pump P arranged in the pump accommodation chamber is opened in the fuel flow-in chamber 6, a pump discharge passage Pb is connected to a fuel discharge passage 8 provided on a pump cover 2, and a pump vapor discharge passage 12 is opened above the pump accommodation chamber. A fuel flow-in passage 19 and a filter vapor discharge passage 20 are opened in a filter accommodation chamber 17 of a fuel filter unit F, and a fuel flow-out passage 18 is connected to an inner part of a filter Fa in the filter accommodation chamber 17. Both the fuel pump module unit G and the fuel filter unit F are attached to a fuel tank T. The fuel flow-in passage 19 is connected to a fuel take-out pipe 33 via a first fuel pipe 34, and the fuel flow-out passage 18 is connected to the fuel suction passage 9 via a second fuel pipe 35.
