The fuel system is controlled by the Powertrain Control Module (PCM).

The fuel system components consist of:
- two-phase fuel pump.
- high-pressure oil pump.
- fuel filter.
- oil pressure regulator.
- fuel pressure regulator.
- high-pressure oil pump reservoir.

Fuel is drawn from the fuel tank by the fuel pump then under low pressure is circulated through the fuel filter and back to the fuel pump. To be circulated under high pressure to the cylinder head fuel galleries. From there the fuel is delivered to the combustion chambers through the electronically controlled/hydraulically actuated fuel injectors.
