PROBLEM TO BE SOLVED: To provide a fuel injection system having a coil part integrated fuel distribution pipe which can be easily regulated and manufactured, and a method of regulating it. SOLUTION: In this fuel injection system comprising a coil part 2 integrally formed with the fuel distribution pipe 1, a drive part 3 is integrally connected to a valve seat 311 of a valve part 31, and it has a casing 30 opened at both ends for holding a plunger 32 to be freely capable of making linear displacement. The easing 30 acts as a yoke part of an electromagnetic injector, and it contains the plunger 32, a valve closing spring 33, and a stopper 34 for regulating a base end position of the valve closing spring 33. The maximum lift quantity of the valve part 31 is decided by collision between a valve element 312 of the drive part 3 and a stopper 313. The drive part 3 can thus be tested before it is assembled with the coil part 2.
