Abstract
A fuel vapor vent assembly with liquid trap is incorporated in a vent valve mounted on a motor vehicle fuel tank. The vent valve operates to vent the fuel tank through a vertically oriented orifice in the vent assembly when the valve is in a normal upright position and closes the orifice when the fuel tank together with the valve is tipped to a significant degree from this position. An elevated liquid trap is provided in the vent assembly at the outlet of the orifice that traps liquid from the venting fuel vapor while permitting venting to continue therethrough and then drains the trapped liquid back past the valve into the tank when the pressure in the latter is relieved. An insert mounted in the valve body is adapted to define both the orifice and liquid trap.
