摘要：
A system and method provide dual level pressurization control of a fuel supply system based on whether fuel is being supplied to one or more secondary fuel loads. Fuel pump discharge backpressure is maintained above either a first minimum pressure value or a lower second minimum pressure value by determining whether fuel is being supplied to one or more secondary fuel loads. The fuel pump discharge pressure is maintained above the first minimum pressure value if it is determined that fuel is being supplied to the one or more secondary loads. The fuel pump discharge backpressure is maintained above the lower second minimum pressure value if it is determined that fuel is not being supplied to the one or more secondary loads.
