The invention discloses a vehicle fuel feed piece for facilitating loss reduction. The vehicle fuel feed piece comprises a gas pipe body positioned between a fuel cavity and a nozzle; the gas pipe body includes a straight pipe part and a bent pipe part integrally molded; one end of the straight pipe part and the fuel cavity are integrally molded through an electric melting added material manufacturing process; the inner diameter of the connecting place between the straight pipe part and the fuel cavity is gradually reduced by y=log (2) X in a direction of the fuel cavity pointed to the straight pipe part, wherein X is a natural number; one end of the bent pipe part is connected with the nozzle; the inner diameter D of the bent pipe part is 50-70 mm; the curvature radius is 1.5-1.8 times of the inner diameter of the bent pipe part; and the wall thickness of the bent pipe part is 1.5-2 mm. The vehicle fuel feed piece solves the problems of higher loss of liquid fuels in a traditional engine combustion chamber f
