Fuel tank with suction system

A fuel tank with a suction system, said tank configured to receive at least two layers of liquid, with a lower layer being denser than an upper layer, the upper layer comprising fuel, said suction system comprising:

• a first pipeline comprising, respectively, a first and a second extremity, said extremities each comprising, respectively, an orifice,
• a second pipeline comprising, respectively, a first and a second extremity, said extremities each comprising, respectively, an orifice,
• a third pipeline comprising, respectively, a first and a second extremity, said extremities each comprising, respectively, an orifice,
• a second orifice of the first pipeline being connected to a first orifice of the second pipeline via a vacuum pump,
• a second orifice of the second pipeline being connected to a first orifice of the third pipeline via a valve,
• a second orifice of the third pipeline being connected to a fuel engine,
• a flexible hose comprising a first and a second extremity, said second extremity comprising an orifice configured to connect to a first orifice of the first pipeline via a connection point,
• the first extremity of said flexible hose being fastened to a floating system and comprising at least one orifice, such that the flexible hose orifice is a suction point configured to supply the engine from the upper layer of fuel available within the tank, in order to avoid any water or dirt from the lower layer of liquid.
