One end of a float arm is connected to a float and the other end thereof is rotatably supported by a housing made of insulating resin material. An electrically conductive portion, which is for example made of conducting resin material, is integrally formed with the housing and electrically connecting the other end of the float arm to a ground terminal which is fixed to the housing. A detecting circuit is accommodated in the housing. Electric charge generated at the float due to friction between the float and fuel is grounded to the earth via the float arm, the electrically conductive portion and the ground terminal, so that an adverse effect of the electric charge to the detecting circuit can be avoided.
