The secondary steering pump (5) and the electric motor (4) are beneath the hydraulic oil tank. Gravity causes the oil to flow from the tank through the hydraulic line to the pump inlet. The pump activates. The oil moves around the gears and flows out of the outlet. The oil flows through the relief valve (6) and oil line. Then, the oil flows through the check valve (8). The check valve (9) blocks the oil's flow. The oil flows into the metering pump (2).
