Fuel pump replacement for a 2006 xc70

[monochamus]

So that

My fuel pump is making a "buzz" while works... I think it is "game over" for the pump....

And before it leaves me walking far away from home , I would like to change it, so I need (please) the direct replacement part number.
Volvo sells the entire assembly but I think that replacing just the pump it will be fine.
Anyone can help me ? Which pump can I put on the XC? It would be great if is the original one...

Thanks in advance
