A primary (48, 348, 648, 908) and secondary (50, 350, 650, 910) filter are combined into a single housing (42), and two elements are combined into a single element (46). The primary and secondary filters are fluidly isolated from each other. The primary filter is configured for radial flow, and the secondary filter is configured for axial flow. The filter arrangement can be a top load arrangement or, in another embodiment, a bottom load arrangement. This combination is useable in any system that has a filter upstream of a pump (44) and a filter downstream of a pump (14). The example described is a fuel system. Methods of servicing include simultaneously removing the housing cover along with both the primary and secondary filters.
