To provide a fuel injection apparatus preferable for a marine engine which can
prevent a metal soap from being generated in a motor portion of a high pressure
electric pump even when fuel containing sea water is sucked into the electric pump,
a high pressure electric pump (HP) is provided with a pump portion (P) and a motor
portion within a pump housing (1), the pump portion (P) sucks fuel within
a vapor separator (V), high pressure fuel the pressure of which has been increased
by the pump portion (P) is discharged through the periphery of the motor portion,
the motor portion of the high pressure electric pump (HP) is formed as a brushless
motor portion, and a resin material is molded on the outer periphery of a drive
coil (6B) constituting the brushless motor portion, thereby shutting off
contact between the drive coil (6B) and the fuel.
