Swapping the prssure and return lines on an older Mercedes power steering gear would shoot 3K PSI hydraulic fluid up the steering column and into the interior of the car as soon as the engine started. Leather upholstery and hydraulic fluid don't play well together! That mistake usually totalled the car. At least GM put different size fittings on their P/S boxes to make them idiot-proof!
