Patent ID: 8485389

Claim:
An assembly mounted to a fuel tank within an internal space in the fuel tank and connected to a carbon canister comprising: a housing within the internal space and defining an internal cavity; wherein the housing has a first port and a second port both in fluid communication with the internal cavity; a vapor vent valve within the internal space having an inlet and an outlet; wherein the vapor vent valve permits fluid communication from the fuel tank through the vapor vent valve from the inlet to the outlet; wherein the vapor vent valve is isolated from the internal cavity such that fluid flows through the vapor vent valve from the inlet to the outlet without fluid communication with the internal cavity; a first vent line within the internal space, connecting the outlet of the vapor vent valve with the first port; a second vent line within the internal space and connected to the second port and operatively connected with the carbon canister, fluid flow from the fuel tank to the second vent line thereby passing through the vapor vent valve, then through the first vent line, and then through the housing; wherein at least a portion of the first vent line is above a predetermined liquid fuel level within the tank when the fuel tank and tilted at up to a predetermined angle, thereby preventing liquid fuel from reaching the carbon canister; and wherein the first vent line extends from the vapor vent valve outlet at the housing to the first port.
