Abstract:
A system for delivering fuel to an engine including a fuel reservoir pump configured to pump fuel from a fuel tank to a fuel pump reservoir. A low pressure fuel pump is configured to pump fuel out from within the fuel pump reservoir and to the fuel reservoir pump. A high pressure fuel pump is configured to pump fuel to the engine. The low pressure fuel pump is configured to pump fuel to the high pressure fuel pump. A controller is operable to configure the low pressure fuel pump in a high mode at a first pump rate when the high pressure fuel pump is in a first configuration, and operable to configure the low pressure fuel pump in a low mode at a second pump rate when the high pressure fuel pump is in a second configuration different from the first configuration, the first pump rate is different from the second pump rate.
