The present disclosure is directed to a capsule configured to direct fuel flow within a fuel filter assembly housing. The capsule has a tubular element configured to define a flow path between the capsule and a fuel filter assembly housing. The tubular element defines an interior chamber, a proximal end, and a distal end defining a manifold. The tubular element is configured to be removably received by the fuel filter assembly housing. The interior chamber is configured to receive a fuel filter element. The capsule is configured to direct fuel flow from the proximal end of the capsule, around the tubular element, to a point beyond the distal end of the capsule, and to receive fuel flow from the point beyond the distal end of the capsule and direct the fuel flow via the manifold to the filter element, thereby providing at least two passes of the fuel flow through filter elements within the fuel filter assembly housing.
