Claim:
A diesel fuel purifier unit comprising: an external body having a fuel inlet pipe for the introduction of contaminated diesel fuel, a purified diesel fuel outlet for the passage of a purified diesel fuel, and a drain outlet for the draining of accumulated contaminants, both said inlet and said purified diesel fuel outlet being situated in an upper portion of the external body; a purification chamber encapsulated by said external body, said purification chamber having a barrier with a conical and a cylindrical portion; a first wire filter surrounding the conical portion of said barrier; a second wire filter filling a portion of an annular region between said cylindrical barrier portion and said fuel inlet pipe, said first and second wire filters dividing said purification chamber into a filtered region and unfiltered region; a relief valve connected to an upper portion of the external body; a heating element connected to a lower portion of the external body; a water level sensor connectable to sound and light indicators at a cabin dashboard for detecting the level of accumulated contaminants; and a drainvalve connected to the bottom of the external body at said drain outlet, to permit accumulated contaminants to be drained from the purification chamber; wherein contaminated diesel fuel to be treated flows through the fuel inlet pipe to said conical portion, where the contaminated diesel fuel comes into contact with said heater and is permitted to settle by gravity into a diesel fuel stream and a contaminant layer, said diesel fuel stream then passing through one of said first and second wire filters to said purified diesel fuel outlet.
