Abstract:
1. Fuel tank with at least one filler pipe enclosing a refueling duct and with at least one vent line, which comprises at least one first and one second line section, the first line section extending from a vent connection of the fuel tank to a connection on the filler pipe, and the second line section extending from a connection on the filler pipe to a fuel vapor filter, wherein at least one of the first and second line sections open directly into the filler pipe via at least one connection fitting such that a flow of fuel vapor in at least one of the first and second line sections will flow directly into the filler pipe via the at least one connection fitting without first flowing through an added droplet separator, and wherein the at least one vent line is open to provide venting during a refueling and an operation of the fuel tank; and wherein the at least one vent line and the filler pipe are arranged to provide an increase in a cross-sectional area such that liquid droplets within the fuel vapor separate and flow back to the fuel tank.
