Embodiments herein relate to fuel monitoring systems and related methods. In an embodiment, a fuel monitoring system for a vehicle is included having a fuel filter sensor device configured to generate data reflecting a filter restriction value of a fuel filter, a geolocation circuit configured to generate or receive geolocation data, and a system control circuit configured to evaluate the sensor data to determine changes in the filter restriction value. The control circuit can receive fuel level data, cross-reference geolocation data and fuel level data to identify refueling locations utilized, and correlate refueling locations with subsequent changes in filter restriction to identify an effect of specific refueling locations on fuel filter loading. In some embodiments, a refueling guidance system for a vehicle is included that can provide route and/or refueling site recommendations based on fuel filter loading rate data. Other embodiments are also included herein.

A filter element of a filter for liquid, a drainage closure element, a housing part, and a filter are described, wherein the filter element has a filter medium which continuously surrounds circumferentially an element interior relative to a virtual axis and is connected to an axial end body. The end body is provided with a filter element drainage opening surrounding the axis and communicating with the element interior. A filter element sealing surface or filter element seal surface of a filter element sealing device is provided at the end body and continuously surrounds circumferentially the filter element drainage opening. The filter element drainage opening is closed by the filter element sealing device when the filter element is mounted in the filter housing of the filter. The filter element sealing surface or filter element seal surface is axially oriented with at least one direction component relative to the axis.

An oil pressure supply device supplies, to an oil chamber, an oil pressure generated by suctioning oil from an oil source with an oil pump. The oil pressure supply device includes a first oil passage connected to a suction side of the oil pump; a first check valve provided in the first oil passage and configured to close the first oil passage and prevent oil from moving to the oil source side when the oil pump is stopped; a second oil passage connected to a discharge side of the oil pump; and a second check valve provided in the second oil passage and configured to close the second oil passage and prevent oil from moving to the oil pump side when the oil pump is stopped. When the oil pump is stopped, the second check valve closes the second oil passage earlier than the first check valve closes the first oil passage.

A filter device for treating fluids, in particular for filtering fluids such as fuel, oil, or water, has a housing (56) with a housing pot (58), a housing cover (60), at least one inlet (88) for the fluid to be treated, and at least one outlet (82) for the treated fluid. A connecting head (12) has at least one feed (16) for the fluid to be treated and connectable to the at least one inlet (88), and/or at least one discharge (18). The connecting head (12) and the treatment element (14) can be connected to each other by means of a releasable bayonet-type connecting device (34) through the execution of a rotational/plug-in movement about a connecting axis (20) of the treatment device (10).

An oil separator for a compressor comprising a tank and a lid for the tank, which comprises, in an integral manner, a valve body defining an outlet duct of the separator, a head of a coalescence filter, a body of an anti-condensate valve, a body of a minimum pressure valve and the relative connection ducts.

A fuel filter monitoring method includes receiving pressure signals that are indicative of a pressure drop across at least one fuel filter of a fuel supply system configured to supply fuel to at least one fuel injector of an internal combustion engine and receiving a condition signal indicative of a condition of a fuel supply system, the condition signal being generated by one or more of a geographic location sensor, an altitude sensor, and/or a fuel temperature sensor. The method includes estimating a remaining life of at least one fuel filter of the fuel supply system based on the pressure signal and the condition signal and outputting a notification indicative of the estimated remaining life.

An arrangement and method for determining the service interval of a fluid filter includes a filter and a pump driven by an electric motor. A control module calculates pressure drop across the filter by way of voltage, current, and/or PWM provided to the electric motor. The control module monitors the rate of change of the pressure drop across the filter over the life of the filter. The volume flow rate of the fluid may or may not be held constant. If an abrupt or sudden characteristic change in the pressure drop across the filter occurs, or if the pressure drop across the filter exceeds a threshold amount, the arrangement and method provides a notification that either the filter needs to be replaced or serviced, or that it is probable that a mechanical condition has developed, depending upon the characteristics of the change in pressure drop across the filter.

A system is provided for removing oil from an oil filter of a motor vehicle. The system includes a housing with a top rim, an upper portion, a lower portion, and a bottom rim. The top rim of the housing includes a first diameter. The housing includes the bottom rim with a second diameter that is less than the first diameter. The system also includes an upper cap with a flange including a first side and an opposing second side. The flange is disposed at a top portion of the upper cap. The first side of the flange is coupled to the top rim of the housing. A bottom portion of the upper cap extends into the housing. The upper cap includes a central aperture for draining the oil from the oil filter into the housing.
