If the pump is installed above the liquid level, a non-return valve must be fitted in the inlet pipe below the liquid level. See fig. 4. Self-priming pumps We recommend an opening pressure of the non-return valve which is lower than 0.05 bar. Otherwise, the additional resistance will reduce the suction capability of the pump.

Power Steering Pump Service Manual - TRW Aftermarket

The EV pump requires an inlet line to supply oil to the pump and an outlet line to take the oil supplied by the pump to the steering gear. All excess (bypass) oil is diverted internally in the pump housing back to the inlet of the pumping element. Other systems may have a third line which takes this excess oil back to the reservoir.
