ABSTRACT:
A fuel filter system for conditioning fuel flowing from fuel supply means to an internal combustion engine, comprising a fuel filter head having a contaminant outlet port, and fuel inlet and fuel outlet ports respectively adapted for connection to the fuel supply means and to the internal combustion engine. The fuel filter system further includes a fuel filter cartridge having a filter element, with the fuel filter cartridge having an upper portion releaseably secured to a lower portion of the fuel filter head, defining fuel inlet and fuel outlet chambers which direct fuel from the fuel inlet port and fuel inlet chamber through the filter element to the fuel outlet chamber and fuel outlet port of the fuel filter head. A liquid bleed tube extends between the fuel filter head and the fuel filter cartridge, and a fluid flow conduit connects the bleed tube in fluid flow communication with the contaminant outlet port. An air bleed passageway in the fuel filter head connects an upper portion of the fuel filter cartridge to the fluid flow conduit which connects the bleed tube to the contaminant outlet port. Water, air, and other fuel contaminants separated from fuel in the fuel filter cartridge are continuously removed via the liquid bleed tube and air bleed passageway and delivered to the contaminant outlet port of the fuel filter head during operation of the internal combustion engine.
