ABSTRACT:
A fuel system for an engine is disclosed. The fuel system has a first source configured to pressurized fuel to a first pressure, and a second source configured to pressurized fuel to a second pressure. The fuel system also has a fuel injector configured to receive fuel at the first pressure and the second pressure, and a valve disposed between the fuel injector and the first and second sources. The valve is configured to modify the pressure of fuel from the first source based on a pressure of fuel from the second source.
