The system is driven by single, but instead; 2 stage, Gerotor pump off the front crankshaft snout as in the LS1/LS2/LS6. This is accomplished with 2 seperate internal channels which are evident on the pump face plates. You can see the keyed drives on the External Pump shot and can see both internal gerotor mechanisms in the Internal View which are regulated by a single pressure spring. Notice how the single large oval sump inlet is on the left side (driver side) of the pump and the reservoir inlet/outlet is on the right side (pass. side).
Notice that the reservoir inlet and outlet bosses are both at the bottom (bottom right side of pan and bottom of reservoir). The inlet is not at the top and entering on the side of the reservoir as most dry sump tanks to swirl and deair the oil. But you can see the inlet pipe rises to the top center of the tank internally and "spills" the oil at the top center. You can also see deairing baffles and seperators in the tank lid. The cylinder volume of oil fluid will feed the tank outlet and gravity/pressure feed to the pump inlet boss.
I am assuming that the pump outlet that feeds to the pan outlet will feed the engine oil cooler and then back to the reservoir inlet. I am also assuming that the internal pump outlet will feed to the oil filter and then the engine priority main gallery. Notice that the Filter boss is in the same position as previous LS Gen IV engines.
