The utility model discloses an oil channel one-way valve of a diesel engine fuel filter base. The one-way valve comprises a valve plate (2), a sealing fin (6), a reed (5), a locating plate (4) and a screw (3), wherein the valve plate (2) is inserted onto a fuel filter base body (1), the sealing fin (6) is arranged on the reed (5) and the sealing mouth of the sealing fin (6) is pressed on the valve plate (2) by the elasticity of the reed (5) and the locating plate (4) is pressed on the reed (5) and is fixed on the fuel filter base body (1) with the reed (5) through the screw (3). The oil channel one-way valve of the diesel engine fuel filter base has the advantages that the structure is simple, sealing is reliable, because the locating plate (4) is pressed on the reed (5) so that the locating plate (4) can prevent the sealing fin (6) from overturning and losing efficiency under shocks of mass flow and guarantee the stability when working.
