Abstract
A fuel system a main fuel pump sub-system (MFP) with an inlet for receiving a supply of fuel from an inlet line. The MFP has a main outlet line configured to supply fuel to a main fuel throttle valve assembly (MFTV), and a cross-over outlet line. A variable displacement pump sub-system (VDPP) has a first inlet connected in fluid communication with the cross-over outlet line, a second inlet connected to a branch of the main outlet line, a first outlet line configured to connect to supply fuel to the MFTV, and a second outlet line configured to connect to supply fuel to an actuation system.
