Abstract
An engine fuel system and methods are provided. The engine fuel system includes a supply arrangement for providing an outlet flow of fuel to a bypass metering arrangement. The bypass metering arrangement in turn provides a metered flow of fuel to a parallel metering system including a primary regulated circuit and one or more secondary metering circuits. The bypass metering arrangement is operable to maintain a substantially constant pressure differential across a fuel metering valve thereof, as well as provide the metered flow of fuel in response to downstream pressure demands of the parallel metering system.
