PROBLEM TO BE SOLVED: To make a prefilter eliminatable while maintaining high fuel filtration performance and make a demand level of pressure resistance performance to a fuel filter reducible.SOLUTION: A fuel injection device has a fuel filter 8 disposed between a fuel tank 4 and a feed pump 5 and is configured to return a part of the fuel discharged from the feed pump 5 between the fuel tank 4 and the fuel filter 8 via a reflux fuel passage 9. With this, the fuel returned between the fuel tank 4 and the fuel filter 8 is filtered in the fuel filter 8 again, and therefore high fuel filtration performance is obtained. As the fuel filter 8 is disposed on the upstream side of the feed pump 5, a prefilter can be eliminated. |
