A main pump and control sub-system (MPCS) has a main inlet connected in fluid communication with the supply line downstream of the second outlet of the APS, and a main outlet for supplying fuel to a downstream gas generator. An afterburner pump in fluid communication to supply an afterburner control. An afterburner selector valve (ASV) in fluid communication with the MPCS, the wash line, and the afterburner pump.
