In-tank fuel pump apparatus having improved structure for dissipating electrostatic charges

摘要

A fuel pump apparatus disposed within a fuel tank which may be employed in automotive vehicles is disclosed. The fuel pump apparatus includes a fuel pump, a filter, and a conductive member. The fuel pump is disposed within a conductive pump housing. The filter includes a filter element and a conductive filter casing. The filter element removes particles contained in fuel which is discharged from the fuel pump and returned to the fuel tank. The conductive member electrically connects between the pump housing and the filter casing for dissipating electrostatic charges generated by the friction between the filter element and the fuel passing through the filter element.
