530d E39 Vacuum leak

[Bossman]

Here is a picture of the short piece of vacuum pipe that I had to replace
on the inlet to the vacuum pump. See how cracked it was.

More like a boost leak then?

What is the age/mileage of the car? I'm going to replace all my small vacuum lines this weekend, they also perish with age(not so much mileage).

No this is a diesel, there is no boost at the vacuum pump,there is only boost on the inlet manifold, this piece of pipe is,
mounted in the inlet to the camshaft driven vacuum pump.
The car is a 2002 E39 530d with 210000 on the odo.

Sorry, wasn't paying attention. Also didn't realize the pipe was a small one... I now know which one it is, will have to replace it as well.

so did fixing this pipe better your performance or consumption in any way?
