    Abstract: A fuel filter element includes an upper endcap, lower endcap, and a tubular filter media extending between the two. A water separator is located substantially within a first annular space defined by the filter media, with which it axially overlaps. A pin projects from the lower end of the filter element to fill a drain at the bottom of a filter enclosure. The filter element supports two seals of different diameters, axially offset from each other and configured to receive a standpipe to define a flow path for separated water to enter the standpipe. The filter element may include a drainage cap which defines an open volume and receives water draining through the lower endcap from a second annular space between filter media and a water separator. The invention further relates to an assembly including a standpipe and configured to mate with the disclosed filter element.
