Abstract
A filtration system is configured to provide clean fuel to a running combustion engine. The filtration system may be configured to be connected to a main fuel tank for storing contaminated fuel, and to be connected to a fuel supply of a combustion engine. A filtration circuit may include at least one filter, a first auxiliary fuel tank for containing fuel, and a first fuel pump configured to pump the fuel from the first auxiliary fuel tank through the filtration circuit back to the first auxiliary fuel tank. A second auxiliary fuel tank may be connectable to said first auxiliary fuel tank for receiving fuel from the first auxiliary fuel tank via a transfer valve. A control unit may be configured to control the transfer valve such that the first auxiliary tank is fluidly connected to the second auxiliary fuel tank only if fuel of a desired contamination level is contained in the first auxiliary tank.
