Abstract: A filter module for filtering fuel in an engine system includes a primary filter, a secondary filter, and a module housing. A drain valve is movable between a closed position blocking a drain port in the module housing, and an open position. A service valve assembly is positioned at least partially within a cross passage in the module housing and adjustable from a closed configuration blocking a primary-side fuel passage from a secondary-side fuel passage in the module housing, to an open configuration, to drain fluids from the filter module by way of the single drain port.

Abstract: A filter center tube includes a plurality of layers of solidified material including a first layer with a first undulating strip of solidified material extending in a first predetermined direction, and a second layer with a second undulating strip of solidified material extending in a second predetermined direction. The first layer is in contact with the second layer and the first predetermined direction is not parallel with the second predetermined direction, forming a plurality of pores therebetween.

Abstract: An endcap for a filter element includes an annular plate member disposed adjacent an axial end surface of an annular filter medium of the filter element. A radially outer annular flange projects axially from a surface of the annular plate member. The radially outer annular flange includes a winglet feature extending radially outwardly in a cantilever fashion from an outer circumferential surface of the radially outer annular flange in a direction opposite to a direction in which the filter element is rotated during installation into a filter base of a filter system, with the winglet feature deflecting toward the outer circumferential surface of the radially outer annular flange through contact with a wedge-shaped protrusion projecting radially inwardly from an inner circumference of the filter base as the filter element is rotatably installed into the filter base, and springing back to its undeflected configuration after passing the wedge-shaped protrusion.

Abstract: An anti-prefill device may be disposed at a radially central portion of an endcap mounted on one axial end of an annular filter medium in a filter system. The anti-prefill device includes a first, annular, fluid receiving portion including an externally threaded engagement surface configured to be threadingly engaged with a central, internally threaded boss of a filter base of the filter system at the axial end of the annular filter medium, the first, annular, fluid receiving portion defining an annular concave recess open upwards toward the filter base of the filter system, and a second, annular, fluid blocking portion configured as a cylindrical cap overlapping a radially central tubular portion of the first, annular, fluid receiving portion that projects upwards toward the filter base from a radially inner extent of the radially central portion of the endcap, the second, annular fluid blocking portion being oriented with a concave recess of the cylindrical cap open downwards toward the first, annular, fluid receiving portion.
