The pressure line is the high-pressure side of the power steering system. It carries fluid from the pump to the steering gear to supply hydraulic steering assist. Signs this part may need replacing include fluid seeping or dripping from the hose or its fittings, a fluid level that keeps dropping, a whining pump, or steering that feels heavier than normal. Other components can cause these symptoms, so diagnose the cause before replacing the hose.
