A fuel purge system for a combustion turbine engine fuel supply system (32) to remove fuel from the fuel system (32). The system (32) includes a fuel supply line (40, 42, 44) for supplying fuel from a fuel source (38) to a plurality of burner nozzles (41, 43, 45) of the engine (34). A bi-directional flow divider (52a, 52b, 52c) is located in the fuel supply line (40, 42, 44) for receiving fuel from the fuel source (38) on an inlet side of the flow divider (52a, 52b, 52c) and for dividing the fuel to a plurality of fuel output lines (60, 62, 64) connected to the plurality of burner nozzles (41, 43, 45). A purging fluid line (88, 92, 96) is connected to each fuel output line (60, 62, 64) for supplying purging fluid to the fuel supply line (40, 42, 44), and a diverter valve (100, 102, 104) and drain line (106, 108, 110) are connected to the fuel supply line (40, 42, 44) on said inlet side of the flow divider (52a, 52b, 52c) for draining the purging fluid and fuel to a drain system (112).
