Claim:
A collection system for a ventilation/pressure-equalizing system, used to aerate and de-aerate a fuel tank, of a motor vehicle, the collection system comprising: a collection arrangement that includes adjacent and separate chambers, wherein a first one of the chambers is used as a temporary storage chamber for liquid fuel and is connected to a return line in the fuel tank, wherein the chambers are configured so that for an approximately horizontal alignment of the fuel tank or the ventilation/pressure-equalizing system, liquid fuel does not travel from one of the chambers into the other of the chambers, wherein the liquid fuel that penetrates the ventilation/pressure-equalizing system is collected in the temporary storage chamber and emptiable via the return line in a case of a horizontally aligned fuel tank and de-aeration lines configured to connect to the collection arrangement, the de-aeration lines configured to aerate and de-aerate the fuel tank, at least one of the de-aeration lines connected to one of a non-return valve and a float-roll-over valve and wherein the chambers are separated by a vertically aligned wall, the wall having a through hole for the gases or fuel vapors.
