ABSTRACT:
The present invention describes a fuel filter assembly useful in the purification of fuels such as diesel, gasoline, jet fuel, kerosene, heating oil and similar liquids. The fuel filter assembled herein described separates solids and semisolids particulates such as algae, microbial growth, fungi and the like from fuel, providing a much cleaner fuel to secondary fuel system, engine and fuel consuming devices. The said fuel filtering assembly comprises a removable lid mounted at the top of an upright vertical housing, a non-disposable removable filter unit enclosed in the internal cavity of the said housing and a multi-purpose base comprising fuel inlet and fuel outlet as internal passages within the said base.
