PROBLEM TO BE SOLVED: To provide a fuel supply device for an internal combustion engine, capable of reducing the number of replacement components while including a plurality of fuel filters, and still suppressing the clogging of filter elements due to the precipitation of wax.SOLUTION: The fuel supply device for the internal combustion engine includes a fuel supply passage 100 for supplying fuel from a fuel tank 2 to an injector 8, including a first fuel filter 3 provided on the upstream side of a feed pump 4 and having a first filter element 32, and a second fuel filter 5 provided on the downstream side of the feed pump 4 and having a second filter element 52. Herein, a filter reflow pipe 108 and a return pipe 107 are provided for allowing the reflow of the fuel discharged from the feed pump 4 from the second fuel filter 5 toward a reflow heater 34 arranged in the first fuel filter 3 at the upstream side of the first filter element 32.SELECTED DRAWING: Figure 1 |
