6.7L Power Stroke – Fuel Supply System

• The DFCM includes the following components:
– low pressure fuel pump
– 10 micron primary fuel filter
– thermal recirculation valve
– water fuel separator (~200ml)
– Water in Fuel (WIF) sensor
– water drain (manual operation)
• After the fuel is conditioned by the DFCM, the clean pressurized fuel is sent to the engine mounted fuel filter                assembly where particles larger than 4 micron are filtered out of the fuel. After the fuel is filtered, it is routed to the      high pressure fuel pump.
