するディーゼルエンジンの燃料供給装置。In a diesel engine fuel supply device comprising a fuel supply path for supplying fuel in a fuel tank to an injection pump via a fuel filter by a feed pump, one end of a bypass pipe is provided on the downstream side of the fuel filter in the fuel supply path. The other end of the bypass pipe is connected to the fuel tank side of the fuel supply passage, and when the pressure of the fuel flowing in the fuel supply passage is low, the bypass pipe is protruded into the fuel supply passage by a biasing member. The bypass pipe is held in communication with the fuel supply passage, and as the pressure of the fuel flowing within the fuel supply passage increases, the bypass pipe is moved in a direction against the biasing member by the fuel flowing within the fuel supply passage. 1. A fuel supply device for a diesel engine, comprising: a relief valve having a valve body that switches between the bypass pipe and the fuel supply path to a closed state.
