The article of the present design relates to a rotation pump for supplying fuel to an internal combustion engine or the like. The rotation pump includes a motor, and an impeller driven and rotated by the motor, and a cylindrical body that houses therein the motor and the impeller. A connector and a cylindrical discharge tube are formed at one end of the body, and a cylindrical intake tube is formed at the other end of the body. When electrical power is supplied to the rotation pump via the connector, the motor is activated so that fuel is drawn from the intake tube and is discharged from the discharge tube.
