Abstract
A vapor vent valve for a fuel pump module, wherein the valve assembly attaches directly to the bottom side of the fuel pump module flange within the interior volume of the fuel tank. When rising fuel exerts a force on the valve assembly pushing the float assembly upwards, the valve head attached to the float assembly seals directly against a valve seat on the underside of the modular flange, covering the vapor release aperture located through the flange, preventing fuel from escaping through the vent aperture. In providing a direct seal of the valve head against the modular flange, additional sealing means and potential emission sources between the valve housing and the modular flange are eliminated.
