As a TDI newbie, can someone explain to me why this fuel pump costs $10k? Does this include a new engine and trans too? Sorry, I'm sure this a stupid question but I just don't see how this happens.

Is there any special maintenance that can be done to prevent it's failure??

Its so expensive because the entire fuel system is replaced as you cannot clean any metal fragments from the pump failure. So anything that is related to fuel is replaced.
