1. A filter assembly having a rotational center defined by a central axis of the filter assembly, comprising:
a functional element including:
an outer circumferential surface extending about the central axis and defining a first axial location and a second axial location, the second axial location positioned above the first axial location and having an orifice between the first axial location and the second axial location; and
a channel for receiving a pin, the channel spaced radially outward from the central axis of the filter assembly and radially beyond the outer circumferential surface; and
a filter element positionable over the functional element, the filter element including:
an upper end disc;
a lower end disc;
a filter material arranged between the upper end disc and the lower end disc;
an opening about the central axis, the opening configured to fit over the outer circumferential surface;
a coalescer positioned axially above the opening and about the central axis at a first radial distance from the central axis, the coalescer positioned such that the coalescer is able to collect and divert water particles to filter out water components present in fuel when the filter element is positioned over the functional element; and
an enclosure positioned about the central axis and below the filter material, the enclosure having an enclosure wall that is at a second radial distance from the central axis that is greater than the first radial distance, the enclosure wall at least partially defining an inner volume that is in fluid communication with the orifice of the functional element when the filter element is positioned over the functional element;
wherein the pin is attached to the filter element at a radially outward distance from the opening for guiding the filter element to be correctly mounted with the functional element; and
wherein the pin extends away from the filter material, and has a seal that extends into the channel to seal within the channel when the filter element is correctly mounted with the functional element.
