A fuel component upper tube socket is mainly formed of a connecting board (2), a surrounding board (3) fixed at an edge of the connecting board (2), and a frame board (4) fixed on the surrounding board (3). A connecting hole A (5) for installing a fuel component guide tube and a connecting hole B (6) for installing a meter tube are opened on the connecting board (2). A plurality of water flow holes in an overall long-strip shape is opened evenly on the connecting board (2). The water flow holes comprise a water flow hole A (201) and a water flow hole B (202), and an included angle greater than 0° exists between axial lines of the water flow hole A (201) and the water flow hole B (202). The advantages and beneficial effects of the upper tube socket lie in that, by changing the shape and arrangement manner of water flow holes, the water flow holes can be evenly arranged, and meanwhile a flow area proportion is increased, so that technical problems of low economic efficiency of an upper tube socket and undesirable flow field distribution of outlets of fuel components are solved.
