Fuel pump lifetime?

Hello together As individuals may have read, I have re-examined my 850s again and with the help of @Zug_Spitzer also got the cruise control back in motion. So now everything is ready to drive in one week to the south of France. But now I have a question about the petrol pump. A friend of mine stayed last year on the holiday drive with a defective petrol pump. He drives a V70I T5, MJ I don’t know. In addition, the screwdriver, who prepared my 850s, told me that this was a relatively common damage. just in the area of my running performance (330Tkm). But here in the forum I have read more about defective relays than about defective pumps. How does this look like with the petrol pump itself? by the way, he has pushed a used spare pump into my hand for the holiday ride. For all cases. And also showed me how to replace the part. Doesn’t seem to be such a witchcraft. However, I’m not being in a screw. It seems to be the opening of the big ring to me. But I had to say something about the big twist. I had to say that I didn’t have to say something about it.
