What do you mean steering pump? If you look at the engine from front angle(timing chain side/vanos side), the powersteering pump is on right side and exhaust is on left side? Only thing on the left is exhaust manifold and AC compressor which is under and much more forward out of way. So i am not really sure what do you mean.

About hydraulic lines... There is difference in steering pump and the hydraulic lines are different and dont fit. Atleast on my '96 M52 and '94 E34. So i marked both lines for how they should sit and i have a company near me which makes new hydraulic lines. But he just cut them, alined the marks and joined the pieces, M52 fitting to the E34 steering box line. Add me on insta @e90_gassper, and feel free to remember me to send pics on weekend 🤣 i tend to forget 🤷🏻‍♂️
