A filtration system having an undulated interlocking housing-endplate interface geometry is described. In the filtration system, a filter element endplate and a filter housing component (e.g., a shell housing, a filter mounting head, etc.) meet at an interface. The filter housing component includes an undulating or repeating pattern that meshes with a matching undulating or repeating pattern on the endplate of the filter element. The undulating or repeating pattern prevents the filter element from freely rotating with respect to the filter housing component of the filtration system.

A fuel water separator comprises a housing that defines an internal volume that receives a mixture. The fuel water separator further comprises a filter element that is positioned within the internal volume. The filter element comprises a first endplate and a second endplate that is located opposite the first endplate. The filter element further comprises a filter media that is coupled to the first endplate and the second endplate. The filter media is structured to separate a dispersed phase from a continuous phase of the mixture. The filter element further comprises a collection sump that is located below the first and second endplate and structured to receive the dispersed phase. The filter element further comprises a retention barrier disposed above the collection sump. The retention barrier comprises a drain opening structured to discharge the dispersed phase through the retention barrier into the collection sump.

A fuel-water separator includes a cartridge assembly and a bowl. The cartridge assembly receives a fuel-water mixture and provides a fuel. The cartridge assembly includes an endplate. The bowl is configured to store water separated from the fuel-water mixture. The bowl is coupled to the endplate. The endplate includes an air vent that receives air from the bowl. The air vent establishes a pressure equilibrium within the bowl and the cartridge assembly.
