A hollow filter element of a fluid filter has a filter element-associated retention/carrier device of a retention/carrier system retaining the filter element in a first housing section of a filter housing during installation/removal in or from a second housing section by rotation and/or insertion movement. The filter element-associated retention/carrier device has a retention/carrier part extending radially and circumferentially and has through holes adjacent thereto extending circumferentially so as to enable a filter housing-associated retention/carrier part of the retention/carrier system to pass through axially. This retention/carrier part has a tensile face extending circumferentially and radially on a side facing away from an end face of the filter element facing the first housing section. This retention/carrier part has a rear side in circumferential direction. A space axially adjacent to the tensile face is connected on the rear side to a through hole for guiding through the filter housing-associated retention/carrier part.

An oil filter adapter device may be used to enable an engine or other machine that was manufactured for using cartridge oil filters to use spin-on oil filters. In some examples, the oil filter adapter may have a docking collar for coupling with an engine, a cylindrical base for coupling with an oil filter housing, and an attachment piece for coupling with a spin-on oil filter. The oil filter adapter may also have a spring disposed between the docking collar and the cylindrical base such that the docking collar is compressible relative to the cylindrical base to allow the oil filter adapter is able to couple to a variety of oil filter housings ranging in size and shape.

An oil deterioration prevention device is provided that can prevent an increase in pressure loss by reducing oilflow resistance. The oil deterioration prevention device may include a filtering unit including a filter element that filters oil, and a deterioration prevention unit including a powdery deterioration prevention agent that prevents deterioration of oil, wherein the deterioration prevention unit includes a passage wall that retains the deterioration prevention agent and forms an oil passage.

A filter monitor system (“FMS”) module is installed on the engine/vehicle and is connected to the filter systems, sensors and devices to monitor various performance parameters. The module also connects to the engine control module (“ECM”) and draws parameters from the ECM. The FMS module is capable of interfacing with various output devices such as a smartphone application, a display monitor, an OEM telematics system or a service technician's tool on a computer. The FMS module consists of hardware and software algorithms which constantly monitor filter systems and provide information to the end-user. FMS module provides necessary inputs and outputs for electronic sensors and devices.

An improved fuel tank is disclosed that includes a plurality of recessed ribs formed in the fuel tank adjacent a fuel filter. The fuel filter is received in a pocket formed in the lateral side of the fuel tank by a front side wall and rear side wall that extend from the lateral side to a recessed wall. The ribs include an inner portion, a transverse portion and an outer portion. The recessed ribs have upper and lower walls that converge toward a base wall.

A filter element having a central axis includes a first endplate having a first central aperture, a second endplate having a second central aperture, a filter material positioned between the first endplate and the second endplate and having an axial passageway extending therebetween and along the central axis, the axial passageway axially aligned with the first central aperture and the second central aperture. The filter element includes a plurality of fingers attached to the first endplate and positioned circumferentially about the central axis and extending parallel therewith, each finger having a lip that extends from a surface of its respective finger for axial engagement with a respective nodule, of a plurality of nodules, of a filter head.

A fluid connection element for a housing element is disclosed. The fluid connection element includes an inlet opening for introducing a fluid into the fluid connection element and an outlet opening for discharging the fluid from the fluid connection element. The outlet opening engages the housing element when the fluid connection element is coupled to the housing element in an installed state. The inlet opening and the outlet opening are coupled via a channel. A valve assembly is arranged in the channel such that the valve assembly is opened or closed as a function of an impulse. The valve assembly in the installed state is arranged at least partially within the housing element.

A method and apparatus are provided for controlling a fuel delivery system to limit acidic corrosion. An exemplary control system includes a controller, at least one monitor, an output, and a remediation system. The monitor of the control system may collect and analyze data indicative of a corrosive environment in the fuel delivery system. The output of the control system may automatically warn an operator of the fueling station of the corrosive environment so that the operator can take preventative or corrective action. The remediation system of the control system may take at least one corrective action to remediate the corrosive environment in the fuel delivery system. One or more sensors may be employed to signal proper operation of the remediation system.

Apparatus that makes it possible to prefill spin-on filter cartridges by allowing users to easily pour fluid only into the filter cartridge input port holes. Particularly useful for applications where introducing contaminants downstream of the filter can be detrimental to the system the filter protects.

A filter arrangement for threadably securing to a filter head includes a housing having a surrounding wall defining an interior volume, an open mouth providing access to the interior volume and an end opposite of the open mouth. The surrounding wall has an exterior and an interior. A filter media construction is operably held within the interior volume. A sleeve, distinct from the housing, is secured to the exterior of the surrounding wall adjacent to the housing mouth and extending partially along the surrounding wall. The sleeve has an exterior and an interior. The exterior of the sleeve defines mounting threads constructed and arranged to removably mount with the filter head, when the filter arrangement is secured to the filter head. The interior of the sleeve is against the exterior of the surrounding wall. A first seal member is oriented against the sleeve to create a seal with a filter head, when the filter arrangement is secured to the filter head. A filter assembly includes a filter arrangement and a filter head. The filter arrangement is removably secured to the filter head by a threaded connection between the sleeve and the filter head. A system includes an engine utilizing a liquid and a filter assembly in fluid communication with the engine to filter the liquid. Methods of making filter arrangements include utilizing structures characterized above.
