Abstract
A fuel filter for the fueling system of a motor vehicle has a non-conductive housing defining a chamber in which porous sintered plastic discs are mounted transversely across the chamber defined by the housing. The discs are of graduated porosity, and tend to strip electrons from the hydrocarbon paraffin of which the fuel consists. The charges generated by the stripping are neutralized by the positive ions generated by an adjacent disc.
