A manifold for a fuel filter assembly includes a first base, which may define a first inlet passage to direct flow to a first filter element, and a first outlet passage to direct flow from the first filter element to a second base. The manifold includes a second base, which may define a second inlet passage to receive flow from the first base and direct the flow to the second filter element, and a second outlet passage to receive the flow from the second filter element. The manifold includes a diverting module, which may provide flow communication between the first outlet passage and second inlet passage, such that flow in the first inlet passage passes through the first filter element before entering the second inlet passage. The first and second inlet passages may define a common longitudinal axis. The first and second outlet passages may define a common longitudinal axis.
