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