ABSTRACT:
A fuel filter having a housing made of an electrically non-conductive material has a chamber disposed within the housing and the housing has an inlet and an outlet both in communication with the chamber. A filter media is disposed inside the chamber and is fluidly disposed between the inlet and the outlet for filtering non-polar substances such as fuel for internal combustion engines or the like. The filter media includes conductive fibers for preventing the buildup of or generation of electrostatic charges which would otherwise be generated by passage of fuel through standard paper filters such as those used almost universally in the automotive industry. These conductive fibers are preferably carbon fibers which consist of approximately two percent (2%) of the entire filter media.
