The fuel system is divided into two sub systems:

• Low pressure system
• High pressure system.

The low pressure system features the following components:

• Fuel tank
• Fuel pump delivery module
• Fuel Pump Driver Module (FPDM).

The low pressure system pressure is 4.5 bar (65.3 lbf/in² ) and the pressure in the high pressure system is up to 150 bar (2176 lbf/in² ).

The high pressure system is described in 'Fuel Charging and Controls'. For additional information, refer to: DESCRIPTION AND OPERATION .

The emissions system is described in 'Engine Emission Control'. For additional information, refer to: DESCRIPTION AND OPERATION .
