Abstract

The present invention relates to a fuel system (5) for an internal combustion engine (3), as well as a method of operating such a fuel system. The fuel system (5) comprises a fuel tank (9), a low-pressure fuel pump (11) arranged downstream of the fuel tank (9), a high-pressure fuel pump (13) arranged downstream of the low-pressure fuel pump (11), and an accumulator (15) arranged downstream of the high-pressure fuel pump (13) for supplying fuel to an injection device (17). The high-pressure pump fuel (13) is arranged to suck fuel from the fuel tank (9) and comprises a fuel-lubricated bearing (21) arranged in fluid connection with a fuel supply inlet (20) of the high-pressure fuel pump (13). A first fuel return line (23) is arranged to fluidly connect the fuel-lubricated bearing (21) to the fuel tank (9). The accumulator (15) comprises a pressure regulating valve (19) fluidly connected to a second fuel return line (25). This second fuel return line (25) is arranged to convey fuel from the accumulator (15) to the fuel-lubricated bearing (21).
