Fuel system for an internal combustion engine

A fuel system for an internal combustion engine, said fuel system comprising:

• a low-pressure fuel delivery unit;
• a high-pressure fuel delivery unit which has a low-pressure region and a high-pressure region such that said low-pressure region supplies fuel to said high-pressure region and such that said high-pressure region pressurizes fuel and supplies the fuel pressurized by the high-pressure region to a plurality of high-pressure fuel injectors;
• a low-pressure fuel rail which supplies fuel to a plurality of low-pressure fuel injectors;
• a low-pressure fuel injector line which is 1) connected at a first end thereof directly to said high-pressure fuel delivery unit and receives fuel from said low-pressure region and 2) connected at a second end thereof directly to said low-pressure fuel rail, thereby providing fluid communication from said low-pressure region to said low-pressure fuel rail;
• and
• a means for reducing fuel pressure pulsations, said means for reducing fuel pressure pulsations being located between said high-pressure fuel delivery unit and said low-pressure fuel rail.
