Abstract: The disclosure relates to a fuel filter assembly, a filter element, and a method of draining water from a fuel filter assembly. The fuel filter assembly comprises a filter element with a water collecting space; the filter element being connected to a fuel pipe for feeding an upstream side of the filter element with fuel and for providing filtered fuel from a downstream side of the filter element to a combustion engine or parts thereof; a fuel pump arranged downstream from the filter element, wherein the fuel pump can be operated in a first mode for drawing fuel through the filter element and in a second, reverse mode for feeding fuel back to the filter element; a one-way fuel valve arranged upstream of the filter element allowing for flow towards the upstream side of the filter element; a pressure-actuated one-way drain valve in communication with the water collecting space.

Abstract: An air filter assembly having a primary filter element, a secondary filter element, and a housing with an outlet tube is disclosed. The primary filter element is operably installed within the housing and has an interior volume. The secondary filter element is operably installed within the primary filter element interior volume and has an interior volume defined by a first wall extending between a closed end cap and an opposite open end cap. The open end cap of the secondary filter element defines a sealing structure having a first portion extending into the secondary filter interior volume. The outlet tube is operably connected to the housing air outlet opening and includes an inset collar being at least partially disposed within the secondary filter interior volume and extending over at least a part of the sealing structure first portion.

Abstract: According to the present disclosure, features, components and techniques useable for providing air cleaner arrangements are provided. Many of the features relate to an axial seal arrangement provided on a filter cartridge. A typical filter cartridge, for use with these features, is a filter cartridge having opposite flow ends. Example media arrangements that fit this characterization are described. Seal arrangements provided with an axial housing sealing engagement surface are shown. A seal arrangement is provided with variations therein, to advantage. These variations can be in either or both of an outer peripheral edge surface and a housing seal engagement surface. Also, air cleaner assemblies having advantageous features therein are provided. Further, air cleaner housings are described, with selected, preferred features for engagement with filter cartridges.
