Abstract
A filter assembly includes a header, a bowl and a replaceable filter element. The bowl is indexed to have a single installed orientation with respect to the header. The filter element is keyed and indexed to both the bowl and the header, with index structures on the filter element engaging complementary coding structures on both the bowl and the header to define a single installed orientation of the filter element with respect to the filter assembly. The filter element lower end cap includes a notch and the filer media defines a longitudinal channel corresponding in position and configuration to the notch in the lower end cap. The lower end cap and channel in the filter media engage a protrusion inside the bowl. The bowl maintains angular orientation (prevents twisting) of the upper and lower end caps when the filter media is exposed to high differential pressures.
