A fuel supply system for a vehicle, comprises a fuel pump (118) disposed in a fuel tank (103), wherein a bottom plate of said fuel tank (103) has a fuel sump portion comprising a step portion (125) and a lower portion (126) located on the lower side of said step portion (125), and a fuel suction port (131) of said fuel pump (118) is located on the lower side relative to said step portion (125) and at an upper surface of said lower portion so as to be located at a roughly central portion in the width direction and the front-rear direction of said fuel tank (103). The fuel suction port (131) of said fuel pump (118) is located in at least one of a space occupied by a fuel in common at the times when said fuel tank (103) is inclined forwards and rearward at respective expected angles and a space occupied by said fuel in common at the times when said fuel tank (103) is inclined leftwards and rightwards at respective expected angles, wherein the amount of the residual fuel in said fuel tank (103) is at a predetermined reserve amount.
