  • Method of manufacturing a fuel inlet
    Patent number: 6615489
    Abstract: A method of manufacturing a fuel inlet having an improved anti-rust property. As material for an inlet pipe 2 and a breather tube 4, stainless pipes are used. A pipe expanding process in which an end portion of the inlet pipe 2 is enlarged in diameter to form a filling part 6, a screw-thread forming process in which a helical groove 12 is formed on a periphery of the filling part 6, a welding process in which the breather tube 4 is welded to the inlet pipe 2, and a coating process in which a cationic electrodeposition coating is applied to a fuel inlet 1 after the welding process are performed in turn, thereby obtaining the fuel inlet 1 having an improved anti-rust property.
