Fuel delivery pump oil returning structure

The utility model belongs to the technical field of automobile components, and provides a fuel delivery pump oil returning pipeline. The fuel delivery pump oil returning pipeline comprises an oil storage barrel and an oil returning pipe which are fixed in a fuel tank, and further comprises a tee-branch pipe. The tee-branch pipe comprises a first oil inlet communicated with the oil returning pipe, an oil outlet communicated with the oil storage barrel, and a second oil inlet communicated with the oil outlet, a jet pump is arranged between the first oil inlet and the oil outlet, the jetting direction of the jet pump faces the oil outlet, and the first oil inlet is communicated with the oil outlet through the jet pump. The second oil inlet is provided with a pressure valve, and the fuel tank is connected or disconnected with the second oil inlet through the pressure valve. The tee-branch pipe is additionally arranged, the jet pump is arranged in the tee-branch pipe, negative pressure is formed through the drainage function, the pressure difference exists on the two sides of the pressure valve, the pressure valve is opened while the fuel pressure outside the pressure valve does not need to be overcome, the fuel flow utilization rate is increased, the oil returning efficiency is improved, and the oil storage barrel can be full of fuel more rapidly.
