Fuel Conditioning Module - F-150

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2018 Ford Transit-350 HD, 2018 Ford Transit-350, 2018 Ford Transit-250, 2018 Ford Transit-150, and 2018 Ford F-550 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

The internal components of the fuel conditioning module include the following:

10 micron fuel filter and water separator
water in fuel (WIF) sensor

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 fuel conditioning module. 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 secondary fuel filter then 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 secondary fuel filter.
