Abstract
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.
Claims24
A fuel-water separator, comprising:
- a cartridge assembly that receives a fuel-water mixture and provides a fuel, the cartridge assembly comprising an endplate having a top side and a bottom side;
- and
- a bowl configured to store water separated from the fuel-water mixture, the bowl coupled to the bottom side of the endplate;
- wherein the endplate comprises:
- an air vent that receives air from the bowl such that the air vent establishes a pressure equilibrium within the bowl and the cartridge assembly:
- and
- a plurality of circumferential ribs positioned adjacent and about an outer peripheral edge of the top side of the endplate and facing away from the bowl.

A fuel-water separator, comprising:
- a cartridge assembly configured to separate a fuel-water mixture, the cartridge assembly comprising:
- a coalescing tube;
- and
- an endplate comprising:
- a top side and a bottom side;
- an axial body received within the coalescing tube;
- an air vent extending through the axial body and in fluid communication with the coalescing tube;
- and
- each of a plurality of circumferential ribs being spaced apart from the axial body and positioned adjacent and about an outer peripheral edge of the top side of the endplate and facing away from a bowl, the bowl configured to store water separated from the fuel-water mixture, the bowl comprising a central body coupled to the axial body on the bottom side of the endplate.
