Abstract: A fuel filter assembly includes a filter housing that forms a cavity, and a center stack. The center stack is positioned within the cavity and includes an axial aperture in the top portion, the axial aperture having a circumferential surface, and a fuel filter. The fuel filter includes a filter center support. The fuel filter also includes a sword positioned along a surface of the filter center support, an end cap, a filter element attached to an undersurface of the end cap, a water separator at a filter base of the fuel filter, and a pin attached to the water separator. When the fuel filter is positioned within the filter housing, the sword engages with a slot of a center stack of the fuel filter housing and the pin aligns with a channel of the housing.

Abstract: A filter includes an end cap having a top surface, and a circumferential collar extending from the top surface, the circumferential collar having a radial surface that engages radially with one or more fingers that extend from an inner surface of a filter housing cover, a filter base, a filter element positioned between the end cap and the filter base, and a pin extending below the filter base.

Abstract: A fuel filter for an internal combustion engine may include a filter housing, a ring filter element arranged in the filter housing, a function carrier engaging in an interior space of the ring filter element, a water collection space arranged below the ring filter element, a first venting part channel, and a second venting part channel. The function carrier may include a clean channel extending therein. The first venting part channel may extend from the water collection space through the function carrier and may be communicatingly connected to an air discharge channel extending in the function carrier. The second venting part channel may extend through an upper end disc of the ring filter element and may be communicatingly connected to the air discharge channel.

Abstract: A fuel filter for an internal combustion engine may include a filter housing, a filter housing cover detachably connected to the filter housing, a filter space delimited by the filter housing cover and the filter housing, and a ring filter element arranged in the filter space. The filter housing cover may include a head portion and a foot portion. The filter housing cover may have at least one foot inner diameter and at least one head inner diameter that extend transversely to an axial direction. The ring filter element may have at least one outer diameter that corresponds to the at least one foot inner diameter. The at least one head inner diameter may be smaller than the at least one foot inner diameter. The ring filter element may form a venting device, which may form at least one venting channel that leads into the head portion.

Abstract: A suction device may include a suction channel, a first valve, and a second valve. The suction channel may include a first suction portion and a second suction portion disposed opposite one another in a transverse direction. The first valve may be arranged in the first suction portion. The first valve may include a first valve seat and a moveable first valve body. The second valve may be arranged in the second suction portion. The second valve may include a second valve seat and a moveable second valve body. When a transverse acceleration is equal to or greater than a predefined transverse acceleration, one of the first valve and the second valve may close while the other one of the first valve and the second valve remains open. When the transverse acceleration is less than the predefined transverse acceleration, the first valve and the second valve may both be open.
