摘要
A fuel system that supplies fuel to an engine of a vehicle. The fuel system includes a pump that pumps fuel and a controller that selectively changes operation of the pump between an electronic returnless fuel system mode and a mechanical returnless fuel system mode. In the electronic returnless fuel system mode, the outlet of the pump is varied, and in the mechanical returnless fuel system mode, output of the pump is maintained approximately constant.
