Regarding the Fuel Pump, my current understanding is that there were serious issues with the first aftermarket ones manufactured but this has been solved.

This is already probably common knowledge but the FP is very tightly controlled by the ECU because fuelling in the FSI engine is very critical. However, the behaviour and interactions between FP and ECU are, I believe, smart. I stand to be corrected but that's my understanding.
All any of us can do is to post information which is to the best of our knowledge at the time.
