摘要

A method for suctioning liquid fuel from a liquid trap in a fuel tank of a motor vehicle, includes generating a negative pressure in a gas compartment or headspace of the fuel tank, applying the negative pressure to the liquid trap through a suction line, wherein the liquid trap has a collection container collecting liquid fuel during venting of the fuel tank, and at least partially suctioning the liquid fuel located in the collection container through the suction line into the gas compartment or headspace.
