<p>A fuel filter (130) includes a housing (132, 133) enclosing a filter element (140) in surrounding relation to a fuel pump (150). A diverter plate (214) assembly supported in the housing (132, 133) in sealing relation with one of the housing portions (132), the pump (150) and the filter element (140), includes a bypass valve (212) with a ball member (256). The bypass valve (212) is normally closed when the pump (150) is operational, and flow passes from the inlet (136), through the filter element (140), and through the pump (150) to the outlet (137). The bypass valve (212) opens when the pump is not operational, and flow passes from the inlet (136) through the filter element (140), and then directly to the outlet (137), bypassing the fuel pump (150). The diverter plate (214) includes a segmented collar (222) that couples the plate (214) to one of the housing portions (132); a lip seal (239) sealing to the pump (150); an outer rim (228) that seals to the housing (132); and an annular flange (238) that seals to the filter element (140).</p> |
