Abstract:
A fuel chamber is formed between a pump arrangement and a motor arrangement, and outer flow passages are formed between a stator of the motor arrangement and a housing. Fuel, which is discharged from a discharge port of the pump arrangement, is outputted to an outside of the housing from a fuel discharge conduit that is formed on a side of the motor arrangement, which is opposite from the pump arrangement, after passing through the motor arrangement. At a time of performing electroplating on the stator, electrode contact portions, to which electrodes can contact, is formed in an outer wall of the stator, which forms the outer flow passages.
