Beschreibung
Zusammenfassung:	A method for the production of a suction jet pump delivering fuel into or out of a fuel tank, wherein the suction jet pump has a flow channel and a nozzle, and wherein the flow channel forms a feed line to the nozzle and the flow channel is formed in one piece with the nozzle, the method including, in the following order: placing a mold core into a matrix to produce the suction jet pump by injection molding and form a cavity between the mold core and the matrix; encapsulating the mold core and filling the cavity formed between mold core and matrix with a plastic; removing the mold core through an installation opening, arranged opposite the nozzle, in the flow channel; and closing the installation opening by thermal deformation, in the edge region of the installation opening, of the plastic used for the production of the suction jet pump.
