A filter assembly comprises a filter housing defining an internal volume, a filter element positioned within the internal volume, and a gasket retainer. An outer edge of the gasket retainer is coupled to a top end of the filter housing, and an inner rim thereof forms a gasket retainer ledge. The filter assembly further comprises a retainer loop comprising a retainer loop main body. A plurality of retainer arms extend axially from the retainer loop main body towards the gasket retainer. Each of the plurality of retainer arms comprise a retainer arm ledge extending radially towards the retainer loop main body and snap-fit to the gasket retainer ledge. A retainer loop sidewall extends from the main body away from the gasket retainer. An outer surface of the retainer loop sidewall defines a curvature. A sealing member is removably positioned around the outer surface of the retainer loop sidewall.

An apparatus and a method are provided for an inline fuel pump for conveying liquid fuel from a fuel source to an intake of an internal combustion engine. The inline fuel pump operates with various fuels, such as gasoline, diesel, biodiesel, gasoline-ethanol blends, as well as commonly used fuel additives. The inline fuel pump comprises an inlet placed into fluid communication with the fuel source. An outlet of the inline fuel pump is placed into fluid communication with the intake. An electric motor coupled with an internal liquid pump convey liquid fuel from the inlet to the outlet. The electric motor and the internal liquid pump are housed within a sealed case configured to protect the electric motor and the liquid pump from an exterior environment. Power leads convey electrical power from an electrical system of the vehicle to the electric motor.

A filter element for a fuel filter has first and second end plates and a particle filter medium arranged between the first and second end plates. A bayonet protrusion on the first end plate is designed to engage a bayonet receptacle of the filter housing by rotation of the filter element about a filter element longitudinal axis. An internal sealing element on the second end plate is designed to separate a raw side from a water collecting chamber of the fuel filter. The filter housing has a filter housing body and a cover screwed onto the filter housing body. The filter housing has a bayonet receptacle arranged on its inner side. By rotating the filter element about a filter element longitudinal axis of the filter element, the bayonet protrusion engages the bayonet receptacle of the filter housing when the cover is unscrewed from the filter housing body.

A filter element is provided with a filter medium and a first end disk connected to the filter medium. A first bayonet protrusion is disposed on the first end disk and designed to engage behind a first bayonet receptacle of a filter housing of a filter. The first bayonet protrusion has a free end. The first bayonet protrusion projects at least over sections thereof in a radial direction relative to a filter element longitudinal axis of the filter element past the filter medium. The free end projects in the radial direction toward the filter element longitudinal axis. A filter with a filter housing provided with a first bayonet receptacle is provided and the filter element is arranged in the filter housing such that the first bayonet protrusion on the first end disk engages behind the first bayonet receptacle of the filter housing.

A no filter no run bidirectional pin element is disclosed. A shell housing is removably coupled to a filtration housing, a removable no filter no run attachment, and a filter element. The filter element comprises a filtration media and a bidirectional pin element. The bidirectional pin element comprises a center tube formed as a single piece with a bidirectional pin. The installation of the filter element and the shell housing into the filtration system results in the bidirectional pin entering a pin aperture of the removable no filter no run attachment and the bidirectional pin preventing the operative engagement of a blocking element with a divider inside the no filter no run attachment.

The filter device includes a case, an element, and a water separator. The case accommodates the element and the water separator. The element removes solid particulates from the fuel. The element can be replaced by opening the case. The water separator removes water content from the fuel. The water separator is held in the case. The water separator is movable relative to the case. The water separator is movable within a movable range. The element and the water separator are provided with a passage connecting member for connecting a fuel passages.

A fuel module for pumping and filtration of a fuel in a fuel system includes a flow housing, and each of an electrically powered pump, a first cartridge filter, and a second cartridge filter in sealed, direct engagement with the flow housing. The fuel module is applied in a low pressure fuel circuit feeding fuel to a high pressure fuel circuit for pressurization to an injection pressure. Electronic closed loop control techniques for the pump are also disclosed.

A filter assembly includes a manifold having a fluid inlet and a fluid outlet, a filter housing having a filter medium provided therein, the filter medium defining an inner filter chamber and defining an outer filter chamber between the filter medium and the filter housing, the filter housing being removably attached to the manifold. The filter assembly includes a valve assembly mounted inside the manifold, and a by-pass channel defined inside the manifold between the fluid inlet and the fluid outlet. The valve assembly includes a valve body, a by-pass valve system, and a shut off valve system. The by-pass valve system includes a by-pass valve piston having a piston body, and a by-pass valve spring arranged to move the by-pass valve piston. The shut off valve system includes a shut off valve piston, and a shut off valve spring arranged to move the shut off valve piston.

The present application relates to the field of fuel filter components of internal combustion engines, and discloses a fuel filter element, including a filter element main body and a protective cover. A fuel return column extends from an upper end surface of the filter element main body. The protective cover is formed with a U-shaped groove adapted to the fuel return column, is adaptively installed on the filter element main body and is of an annular hollow structure. The U-shaped groove accommodates the fuel return column to form a protective assembly. Therefore, the problem of poor sealing caused by installation deformation damage and installation deviation of the fuel return column, and the cost of a hollow structure of the protective cover are reduced.
