The invention relates to a pumping system (2) for a fuel dispensing unit (1), comprising a first pumping unit (3) configured to suck fuel from a fuel storage tank and comprising a first air separator for circulating a part of the fuel with low rate of gas toward a first fuel supply line (15) and to evacuate a gas-enriched part of the fuel toward a first recovery chamber (18), a second pumping unit (4) configured to suck fuel from the fuel storage tank and comprising a second air separator for circulating a part of the fuel with low rate of gas toward a second fuel supply line (16) and to evacuate a gas-enriched part of the fuel toward a second recovery chamber (19), and a manifold (8) comprising a fuel inlet (34) connected to the fuel storage tank, a first fuel outlet (35) connected to a first supply inlet of the first pumping unit (3), and a second fuel outlet (36) connected to a second supply inlet (38) of the second pumping unit (4). The invention also relates to a fuel dispensing unit (1) for refueling vehicles.
