<p>A fuel system (4) for a combustion engine (2) comprises a first fuel tank (20), a second fuel tank (22), a first fuel pipe (36) arranged in connection with the first fuel tank (20) and the second fuel tank (22), a second fuel pipe (40) arranged in connection with the first fuel tank (40), a main feed pump (26), and a transfer pump (28). The main feed pump (26) is arranged to feed fuel from the first fuel tank (20) through the second fuel pipe (40), and the transfer pump (28) is arranged to feed fuel from the second fuel tank (22) to the first fuel tank (20) via the first fuel pipe (36). A water-separating pre-filter (30) is arranged downstream of the transfer pump (28), so that the transfer pump (28) feeds pressurised fuel through the pre-filter (30). A water container (54) is arranged in connection with the first fuel tank (20), so that the water container (54) is in connection with the pre-filter (30) and receives separated water from the pre-filter (30). The fuel system also enables a method to handle water occurring in fuel in a fuel system (4), and which reduces the risk of operational disruptions in a combustion engine (2) and a motor vehicle.</p> |
