1. A fuel tank for an aircraft, comprising a fuel pumping system in said tank, wherein the fuel pumping system comprises:
a set of hoses comprising at least two hoses, a first end of each hose being disposed in a lower part of the tank, the first ends of the different hoses of the set of hoses being distributed over the lower part of the tank;
a fuel pump;
a manifold to which second ends of the different hoses of the set of hoses are connected as input, an outlet of the manifold being connected to the fuel pump;
a set of fuel level sensors such that a fuel level sensor is associated with each hose of the set of hoses and is placed in the vicinity of the first end of said hose; and
a valve associated with each hose, this valve being controlled by a control system configured such that when the fuel level sensor associated with this hose detects a low fuel level, the valve is controlled into a closed position, and otherwise the valve is controlled into an open position,
wherein the tank comprises a partition which partially covers the lower part of the tank and which is spaced apart from a lower wall of the tank in such a way that the first ends of the hoses and the level sensors are situated between the lower wall of the tank and the partition, such that the partition does not contact the lower wall of the tank, and
wherein the tank comprises a set of walls, each extending from the partition to the lower wall of the tank.
