Description Reviews MINI Power Steering Pressure Line for all generation 1 cars. This line goes from the power steering pump to the rack and pinion. Comes with new crush rings for the rack side and a new o-ring on the pump side. This line normally leaks at the crimps where the rubber line meets the metal hard lines. This is not a widespread problem and we only replace a few here at the shop, so don't feel you have to replace it just cause you're in there.
