Abstract
A grounding arrangement for an in-tank fuel system includes a fuel level sensor assembly of a fuel module comprising a conductive card body and a resister card supported on the conductive card body. The resister card includes a conductive trace in conductive contact with the conductive card body. The card body is conductively connected to a conductive fuel module component. The trace is adapted to be connected to the ground plane of a vehicle. Other traces on the resister card are in the electrical circuit of the fuel level sensor assembly. The fuel module further includes a conductive blade having a knife edge and in conductive contact with a conductive fuel module component. The knife edge cuts through the insulation of an insulated conductor to allow the knife edge to be in contact with the conductive element of the conductor.
