  • Filter element with automatic air bleeding
    Patent number: 9186602
    Abstract: A filter element that is provided with automatic air bleeding features to efficiently bleed air from a fuel filter module containing the filter element. The filter element has an upper end cap with one or two air vents. One of the vents provides a bypass for air through wet filter media through which air from the fuel supply may not be able to pass through easily. The inner air vent is located on the inside of a circle formed by attachment clips that attach the respective filter element to a removable cover. The inner air vent allows for air inside the filter module to be easily purged out via a drain hole on the fuel filter module, while providing resistance to fuel. The drain hole is provided on the filter module which is internally connected to the fuel outlet and therefore to the fuel tank.
