Disclosed is a gas injection device (10) for injecting an expulsion gas into a tank for a liquid. The gas injection device comprises an inlet pipe (11) for receiving the gas and a distributor portion (12) for releasing the gas through a plurality of capillary passages (13). The inlet pipe has a first end (111) configured to be connected to a gas supply line and a second end (112) located within a chamber (15) in the distributor portion. The capillary passages (13) respectively extend in a direction adapted to a periphery (151) of the chamber (15).
