A center tube and a central fluid supply tube combination includes a center tube body defining a longitudinal length, and a central reservoir. The center tube also includes an apertured annular wall extending axially the majority of the longitudinal length, and a first annular solid wall extending axially from the apertured annular wall. A central fluid supply tube is disposed in the central reservoir, and includes a second annular solid wall that is radially surrounded by the apertured annular wall of the center tube. The second annular solid wall defines a supply passage with a fully circular flow flux.

Fuel filter passage for downward fuel flow direction

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.

An end cap for a filter element may include an element receiver configured to be coupled to a tubular member, and a base passage receiver in flow communication with the element receiver. The end cap may further include an end cap barrier extending outward from the base passage receiver, the end cap barrier including a first side configured to face a filter base. The end cap may also include end cap flow passages configured to provide flow communication between filter media and a filter base, and including a passage opening spaced a first distance from the first side. The end cap may further include a barrier edge and a peripheral seal, wherein an uppermost surface of the peripheral seal terminates a second distance from the first side of the end cap barrier, wherein the first distance is greater than the second distance.

A filter assembly may include a canister and a filter element received in the canister. The filter element may include filter media configured to promote separation of a first fluid from a second fluid having different characteristics than the first fluid as fluid passes through the filter media. The filter element may further include a first end cap, a second end cap, and a tubular member extending between the first and second end caps. The filter assembly may further include a flow cap associated with the first end cap of the filter element. The flow cap may include an inlet portion configured to provide flow communication between an inlet port of a filter base and the tubular member of the filter element, and an outlet portion configured to provide flow communication between an outlet port of the filter base and an exterior portion of the filter element.

A filter housing is provided. The filter housing includes a circumferential rib provided on an outer surface thereof. The filter housing also includes a first longitudinal rib provided on the outer surface thereof. The first longitudinal rib connects and extends away from the circumferential rib along a length of the filter housing. The first longitudinal rib defines a first thickness thereof. The first thickness tapers towards the circumferential rib. The filter housing further includes a second longitudinal rib provided on the outer surface thereof. The second longitudinal rib is provided opposing the first longitudinal rib. The second longitudinal rib connects and extends away from the circumferential rib along the length of the filter housing. The second longitudinal rib defines a second thickness thereof. The second thickness tapers towards the circumferential rib.

Filter housing

A filter element may include a first end cap including an end cap barrier including an inner end cap aperture and end cap flow passages configured to provide flow communication between the of interior the filter element and the exterior of the filter element. The filter element may also include a first tubular member having a first end coupled to the first end cap to provide flow communication between the inner end cap aperture and a second end of the first tubular member. The filter element may further include first filter media extending around the first tubular member, an intermediate barrier coupled to a second end of the first tubular member, and second filter media having different filtering characteristics than the first filter media. One of the first filter media and the second filter media may include a coalescing-type media configured to promote separation of a first fluid from a second fluid.

Filter element and filter assembly for separating fluids

A flow cap may include an outer ring, an inner ring, an inlet portion, and an outlet portion. The inlet portion may include first portions of the outer and inner rings, and a plurality of arms extending between the first portions of the outer and inner rings, wherein the arms at least partially define an inlet aperture configured to provide flow communication between an inlet port of a filter base and an interior portion of a filter element. The outlet portion may include second portions of the outer and inner rings, and a plate including an outlet aperture providing flow communication between an outlet port of the filter base and an exterior portion of the filter element. The outlet portion may also include a wall, wherein the plate and the wall prevent flow communication between fluid entering the inlet portion and fluid entering the outlet portion.

Filter cap

A connector is provided for connecting a hose coupler to a drain knob. The connector includes a base plate, an appendage, and a lateral projection. The base plate includes an opening configured to allow engagement of the hose coupler to the base plate at a first side thereof. The appendage extends axially from a second side of the base plate and is disposed about the opening. The appendage has a substantially oblong profile in a first plane disposed parallel to the base plate. Further, the appendage has a convex face configured to abut a concave portion of a sidewall of the drain knob. The lateral projection extends radially inward from the appendage. The lateral projection is configured to abut an end face of the drain knob.
