Fuel Conditioning Module - Transit
The internal components of the fuel conditioning module include the following:
- 10 micron fuel filter and water separator
- water in fuel (WIF) sensor
- recirculation thermostat
The fuel pump (FP) assembly supplies fuel from the fuel tank through the fuel supply line. When the fuel enters the fuel conditioning module, water is separated from the fuel before it flows through the 10 micron fuel filter which separates particles from the fuel. The separated water collects at the bottom of the pump. If enough water is collected, the WIF sensor detects it and the PCM illuminates the WIF indicator. The conditioned fuel is then delivered to the high pressure fuel injection pump.
The vented fuel from the fuel pressure control valve returns from the high pressure fuel injection pump, combines with the fuel from the fuel injector return line and enters the unfiltered side of the fuel conditioning module. Depending on the fuel temperature returning from the high pressure fuel injection pump, the recirculation thermostat directs the fuel through the fuel cooler back to the fuel tank or through the fuel conditioning module back to the high pressure fuel injection pump.
