摘要：
A fuel system comprises a fuel line that supplies fuel to an engine at a fuel line pressure. A first fuel pump selectively supplies fuel to the fuel line at a first pressure. A second fuel pump selectively supplies fuel to the fuel line at a second pressure that is greater than the first pressure. A check valve having an inlet in communication with an exit port of the first fuel pump and an outlet in communication with the fuel line is positioned based on the fuel line pressure and the first pressure.
