Powersteering leak, hose/pump seal

Car: 2002 bmw m3 e46

It seems I have 2 power steering leaks. One is at the feeder hose connecting to the pump. The clamp is on too tight and it seems that this sprang a leak. This is where the majority of the leak is from.

There is also a leak coming from the pump itself at the seal right by the pulley. It is very little but I am not sure if its even a leak or just somehow got there from the hose leak.

My Mechanic is charging $143 just to replace the feed/intake manifold hose.
And then $947 for the whole pump and hose to be replaced.

As you can see there is a big difference between the two.



Is it possible I can just replace the seal on the pump? I was told no by the mechanic. And is it common for the seal to be a possible cause for the leak? I know how notorious the hoses are for leaks but I just want to make sure before I spend $800 more.
Also it looks like the price for a new pump is around $600-$700. Or have I not searched hard enough?

That's fair. If I were you I'd have the hoses replaced and monitor the fluid. If it still leaks then replace the pump. It'll cost you a few more $$$ to do it this way if the pump does need replacing, yet the potential savings is worth it.

Thanks taylor192, what I ended up doing was cleaning everything and driving for 2 hours, the leak is coming from the pump seal so Ive opted to just replace the hose and pump myself next weekend

If anyone call help me with the proper part numbers for these parts
the hose I know forsure is 33412229369
the pump though Ive gotten different numbers, 33452239679 and 32412229679

one from the mechanic the other from bmw dealership

Ive looked online and there seems to be more than one pump that fits this car, atleast from what the sites state
