A fuel system (4) for an internal combustion engine (2) comprises a first fuel tank (20), a second fuel tank (22), a first fuel conduit (36), arranged in connection with the first fuel tank (20) and the second fuel tank (22), a second fuel conduit (40), arranged in connection with the first fuel tank (20), a main supply pump (26), and a transfer pump (28). The main supply pump (26) supplies fuel from the first fuel tank (20) through the second fuel conduit (40), and the transfer pump (28) supplies fuel from the second fuel tank (22) to the first fuel tank (20), via the first fuel conduit (36). A valve device (32) is arranged downstream of the transfer pump (28). The valve device (32) comprises an arch block (55), which is arranged to move from an open state to a closed state and thus to lead the fuel flow past the first fuel tank (20). The fuel system reduces the risk of insufficient or non-existing fuel supply to the internal combustion engine in the event of an operational disruption, and enables a method for continued operation, albeit with potentially reduced power. This also secures the operation of the internal combustion engine (2) and a vehicle equipped with such a fuel system. |
