A device for liquefying fuel fractions which are in vapour form in fuel tanks (1), having a suction device (10), a pump (13), a condensation device (16) and a separation and storage device (18). This device has a regulation means, with the aid of which the fraction-air mixture (31), which is displaced by the fuel (30), flowing in during the refuelling of the fuel tank (1) and/or a fraction-air mixture (31) which is produced by air injection by means of an air-injection device (23) can be sucked out and separated.
