 The TD4 has two fuel pumps.
The first is the low pressure (high volume) lift pump that lives in the fuel tank - its sole purpose is to supply fuel to the second high pressure pump.
The second pump is up on the engine and is the injector pump.  Its role is to charge the common fuel rail to the very high pressure that the injectors operate at.
