Abstract

A fuel system for an internal combustion piston engine comprising a first fuel section (20) and a second fuel section (22) in which the first fuel section (20) comprises an first inlet line (20') connecting respective inlets of the injectors (25.1) to a tank (28), and the second fuel section (22) comprises a second inlet line (22') connecting respective inlets of the injectors (25.2) to a fuel tank (32), the second fuel section being arranged to inject the fuel into the combustion chambers (12') for igniting the first fuel, in which first fuel section the inlet line (20') extends from a high pressure pump (30) to the respective injectors (25.1), and a fuel return line (20") of the first fuel section (20) extends from each of the injectors (25.1) to the tank (28). The fuel return line (20") comprises a pressure increasing means (36) arranged to the fuel return line (20") of the first fuel section (20) between the injectors (25.1) and the tank (28).
