Abstract:
1. A fuel supply device for a vehicle, said fuel supply device comprising: a fuel tank configured to be supported by a vehicle frame of a vehicle, and configured to store fuel therein; a fuel pump unit configured to be mounted from below to block an opening of a bottom plate of the fuel tank; a fuel pump disposed in the fuel tank to constitute part of the fuel pump unit, and configured to supply under pressure fuel to a fuel injector of an engine; an upstream side filter pipe configured to disposed below the fuel tank and to communicate with an inside of the fuel tank; a downstream side filter pipe connected to the fuel pump; and a fuel filter unit connected between the upstream side filter pipe and the downstream side filter pipe, and configured to filter fuel fed from the fuel tank to the fuel pump, wherein the fuel filter unit comprises a filter case, and wherein the filter case further comprising an inflow port on one end side thereof into which fuel fed from the fuel tank via the upstream side filter pipe flows, and on the other side with an outflow port configured to deliver fuel to the fuel pump via the downstream side filter pipe, the fuel filter unit further comprising, a filter element housed between the inflow port and the outflow port, wherein when the vehicle is in an upright state, the inflow port of the fuel filter unit is disposed at a position higher than the outflow port and the upstream side filter pipe is disposed at a higher position as the upstream side filter pipe goes toward the upstream side, wherein a fuel temporary reservoir portion communicating with the inside of the fuel tank is disposed at a lower portion of the fuel pump unit, a fuel sucking-out pipe connected with the upstream side filter pipe is disposed on the fuel temporary reservoir portion, and wherein the fuel sucking-out pipe is disposed at a position rearward of and below the fuel temporary reservoir portion.
