Abstract
A fuel filter having improved communication with a contaminant container employs a body with a fuel inlet and fuel outlet having a housing connected at its upper end to the body, the housing having a bottom opening therethrough. A filter element is retained within the housing, the filter element having a bottom end. An interior passageway is provided in the filter element in communication with the body fuel outlet, the exterior of the filter element being in communication with the body fuel inlet. A support plate is positioned within the lower end portion of the housing on which the filter bottom end rests. A contaminant container is supported to the housing bottom. The support plate has a spiral fluid passageway providing communication between the interior of the housing and the contaminant container, the passageway permitting liquid contaminant, such as water, to flow from the interior of the housing into the contaminant container. The spiral fluid passageway serves to substantially isolate the interior of the contaminant container from fluid turbulence within the housing.
