The fuel filter funnel is made of a conductive plastic. It has an upper portion which includes a round plastic base having a pair of openings into which a pair filters are press fit. The filters have Teflon coated, stainless steel mesh, which is housed in plastic skeletal structures. Having multiple filters permits a flow rate of at least 15 gallons per minute. In operation, the plastic base creates a false floor, which helps in fuel flow, while the lower, cylindrical portion of the filter housing, combined with the lip formed around the openings in the plastic base form a “sump” into which water and impurities in the fuel are directed. The lack of pressurization, combined with the non-stick Teflon coating, prevents contaminants from being forced into the filter media, while the plastic parts of the remaining portions prevent contaminants from sticking, as well, thereby making for a unit which requires neither cleaning nor replacement parts. The spout at the bottom of the funnel is shaped and sized so that standard PVC pipe can be fitted to the funnel in order to direct the flow of clean fuel, as desired.
