Abstract: A fuel filter assembly that provides a constant level of least restricted fuel flow through the fuel filter assembly during the useful life of the filter media by utilizing the least possible amount of filter media to provide the least possible pressure differential over the filter media while also providing a constant level of fuel additive by exposing an amount proportional to the filter media required for the least possible restricted fuel flow. The fuel filter assembly utilizes a vertically upward housing that houses a filter media and a fuel additive. The fuel level slowly rises in the housing as the filter media becomes obstructed with contaminants and as the fuel additive dissolves over the life of the filter media. The top portion of the housing is made of a transparent material so that the level of fuel level may be easily determined, thereby allowing for an accurate and simple assessment of the useful life of the filter media and the fuel additive. The housing also provides a multi-purpose aperture provided in the top of the housing to provide for removal and/or replacement of the fuel additive and venting and priming of the housing. The filter media and fuel additive are entirely fabricated from combustible materials so that both may be easily discarded without cost and environmental concerns.

Abstract: By providing a lubricating system with a strategically positioned sight-glass, it is possible to replace an fuel filter without either spilling large amounts of fuel all over or allowing for air bubbles, which can degrade the lubricating system's operation and cause siphoning. The sight-glass is positioned below the fuel inlet and outlet passages but below the filter. Thus, as soon as no fuel is seen in the sight-glass, a mechanic knows that the fuel filter has been substantially emptied of fuel yet the fuel inlet and outlet are still full.

Abstract: This disclosure illustrates a replaceable filter assembly for fluids in which the filter has a shell formed from an injection molded threaded end and an integral blow molded closed end to form a unitary shell. A seal such as a flange is provided adjacent to the threaded end so that a pressure seal can be maintained. A filter medium is supported within the shell so as to direct fluid flow through it to remove contaminants. The shell can be formed from plastic materials such as polyester terephthalate (PET), polyether sulfone (PES), and polyether urethane (PEU). This construction enables an inexpensive filter assembly and, with transparent plastic materials, an indication of the contaminant removal activity within the filter.
