The pickup tube assembly includes at least two oil pickup portions operable to pickup engine oil from at least two different oil pickup locations and a flow control operable to control a flow of engine oil between the at least two different oil pickup locations and the scavenge pump. The flow control includes a suction valve, and movement of the suction valve is controlled by selectively applying a high pressure oil to a head of the suction valve.
