Methods and apparatus are provided for electrostatic discharge mitigation for a fuel module. In one embodiment, the system includes a fuel pump having a power and ground connection for pumping fuel. A fuel filter in fluid communication with the fuel pump, the fuel filter including one or more components made of a non-conductive plastic and having a sulfonated surface covered with a conductive surface formed over the sulfonated surface. The conductive surface is electrically coupled to the vehicle ground plane. A method is provided for mitigation of electrostatic discharge in a fuel module. In one embodiment, the method includes sulfonating non-conductive plastic components of the fuel module to provide a sulfonated layer on the non-conductive plastic components and forming a conductive layer over the sulfonated layer to provide an electrical discharge path for electrostatic buildup resulting from fuel moving through the fuel module.
