General information
The main components of the TdV6 engine fuel system include the fuel tank, fuel pump module, fuel filter, fuel cooler, filler pipe with cap assembly and two fuel level sensors.
The fuel system of the TdV6 engine is a high-pressure injection system with a common discharge line. This system uses a high-pressure pump installed on the engine and driven by it, which provides fuel supply with constant pressure to the fuel collector with a common discharge line, where it is distributed to all injectors.
