Abstract
A valveless fuel tank assembly for a vehicle including a fuel tank having an interior chamber to hold fuel therein. The valveless fuel tank assembly also includes a vapor canister to adsorb fuel vapor in the fuel tank. The valveless fuel tank assembly includes a fill-limit tube connected to the fuel tank and communicating with the interior chamber and a tank vent tube connected to the vapor canister and operatively connected to the fill-limit tube. The valveless fuel tank assembly further includes an oleophobic filter connected to the fill-limit tube to allow vapor fuel to communicate with the vapor canister and to prevent liquid fuel from communicating with the vapor canister.
