Thanks for the info guys!
Yes, the parts thing is getting pretty crazy, you would think that at least Bosch would be Bosch but not even that is true any more. I found that out with wifes X3, the new Bosch alternator is made in China in a Bosch box while the rebuilt alternator is factory rebuilt by Bosch in germany! (and a few dollars more). Even BMW have thier econo line and BMW white box replacement parts that aren't the same as original! As far as the fuel pump, I don't mind switching only the pump if the rest of the assembly isn't prone to failure, especially if there is a chance of getting a more dependable and quiet pump. And yes, the Uro stuff I avoid as well!
