One embodiment is a fuel system for an internal combustion engine including a fuel pump having a fuel pump gear operable to drive the fuel pump to pressurize fuel. The fuel pump gear is offset relative to engine top dead center by a predetermined angle to reduce a sound or noise. The offset can be determined by selecting the minimum sound produced over a range of offsets or operating conditions.
