Abstract: A fuel water separator filter is configured as a filter-in-filter construction with multiple water separating layers to separate water from the fuel. The fuel water separator filter is configured for use on a suction side of a fuel pump, and includes a neck with a radially outward facing seal that in use seals with the filter housing. The filter housing is formed with an isolated water sump that in use is isolated from water that is stripped from the fuel by the first stage of the outer filter.

Abstract: A filter cartridge endplate (12) is described herein that has an integrated flow structure. For example, the integrated flow structure has concentric flow portions disposed at a center of the endplate (12), where a separator (10) is built into the endplate (12) that separates fluid flow. The endplate (12) includes a plate with a major surface, it separator (10) that protrudes axially away from the major surface. The separator (10) includes a first flow portion (14) and a second flow portion (16), where the first flow portion (14) is disposed radially inward relative to the second flow portion (16). The first flow portion (14) includes a channel (22) and the second flow portion includes a channel (24). The respective channels (22,24) are configured to allow axial fluid flow relative to the plate, and configured to allow fluid flow that is localized toward the center of the plate (12).

The filter housing is formed with an isolated water sump that in use is isolated from water that is stripped from the fuel by the first stage of the outer filter. The isolated water sump is formed by a wall within the housing, instead of relying on an outer diameter seal on the filter to form the water sump.

Abstract: A fuel filter system that does not require the periodic draining of a water sump. The system includes a fuel tank for storing fuel and a fuel filter fluidly coupled to the fuel tank for separating water from the fuel. A fuel pump has a suction side and a high pressure side. The high pressure side of the fuel pump is fluidly coupled to the fuel filter for pumping fuel to the fuel filter. A water emulsifier, such as an orifice, is fluidly coupled to the fuel filter to receive water and fuel from the fuel filter and form a water-fuel emulsion. The water-fuel emulsion is supplied to any point in the system on the suction side of the fuel pump, such that the water-fuel emulsion passes through the fuel pump and fuel filter.

Abstract: A no filter no run (NFNR) fluid filter and fluid filter assembly are provided. The NFNR fluid filter assembly includes a fluid filter, a filter head or filter housing, and a bypass flow path. The bypass flow path may be sealed off when a compliant filter is installed. When a non-compliant filter is installed (a filter without a bypass seal), fluid may flow to the bypass flow path.
