A self-cleaning fuel oil strainer, coupled to a continuous fuel flow, that includes a pair of canisters, each having a cylindrical wedge wire fuel oil filter screen. An elongated brush running the length of the screen is disposed between two confining walls also running the length of the screen to form a chamber. A elongated partition, including two sets of apertures, is used, along with the elongated brush, to divide the chamber into two particulate dislodge chambers and a drain subchamber. A drain is in fluid communication with the drain subchamber. During cleaning, the drain is opened and the screen is rotated against the brush for liberating the particulate contaminants and a limited amount of fuel oil into the two dislodge subchambers. The particulate contaminants and the limited amount of fuel oil then pass through the apertures at a high velocity and into the drain subchamber which exits through the drain. Alternatively, a reverse flow of clean fuel oil can be used in combination with the elongated brush, for dislodging the particulate contaminants from the fuel oil filter screen. Finally, another variation of using a reverse flow of clean fuel oil for cleaning purposes is discussed whereby a stationary fuel oil strainer is disposed in a system that isolates the fuel oil strainer from the normal fuel oil flow during cleaning.
