Abstract
A fuel pump to be disposed in a fuel tank to supply pressurized fuel to an internal combustion engine includes a motor section, a pump section including an impeller driven by the motor section and a cylindrical pump housing having a pump passage extending along the outer periphery of the impeller so as to pressurize fuel, a suction filter and a feed passage member disposed around the inlet port of the pump passage. The feed passage member has a smooth feed passage connecting the pump passage and the suction filter. The feed passage tapers off toward an inlet port of the pump passage that opens at a peripheral portion of the pump housing.
