Abstract
A fuel contamination monitor for separating particulate and liquid contaminants from a liquid fuel is disclosed. The fuel contamination monitor has an inner and outer fluid pervious wall forming a cavity therebetween. A tubular filtering element consisting of a plurality of fluid filtering media layers is mounted in the cavity. The plurality of fluid filtering media layers includes an outer layer of particulate matter separating filter media and a layer of superabsorbing media adjacent to the outer layer. The superabsorbing media is backed by a layer of paper media and an inner layer of screen material. The interior of the inner fluid pervious wall communicates with a liquid fuel outlet port. A shut-off valve is provided which interrupts the flow of liquid fuel through the fuel contamination monitor in the event that the media becomes contaminated before effective contaminant separation.
