The exhaust type fuel oil filter element assembly comprises filter paper, a central pipe, an upper end cover (5) and a lower end cover (9), the upper end cover is provided with an extending part (51) serving as an oil outlet of the upper end cover, a gasket (1) is installed at the oil outlet of the upper end cover, and a plurality of exhaust holes (52) are formed in the position, matched with the gasket, of the oil outlet of the upper end cover. The gasket is used as a one-way valve, influences of pressure impact of a filtering system on a power pump are prevented, oil of the filtering system is prevented from flowing back to an oil tank through the power pump, and the gasket can be used for separating oil ways and preventing mutual interference. The exhaust hole is formed in the upper end cover, so that gas in the filter can be exhausted through the exhaust hole and the opening gasket, the air resistance of the upper part of the upper end cover of the filter element assembly is reduced, the utilization rate
