Questionhello, i have a ford 2006, f-350, i changed my fuel filter, and fuel conditiing module, but now i'm getting , an error , message that comes up , ( water in fuel) . i've drained the conditioning mmodule, and un did the batteries , but nothing resets the message . how do i fix it ????
thanks
brian
Answeryou may have damaged sensor in filter housing also there is a bulletin related to this-keep in mind this is a bulletin and not a recall also this may have nothing to do with your particular problem especially since it just happened to start after you changed filter-this is from Alldata a sight you may want to think about purchasing a year subscription if you do a lot of your own work.
Engine Controls - WIF Lamp ON/Flickering

WATER-IN-FUEL (WIF) LAMP ON / FLICKERING
FORD:
2003-2005 Excursion
2003-2007 F-Super Duty
2004-2005 E-Series
This article supersedes TSB 06-6-5 to update the Service Procedure.
ISSUE
Some 2003-2005 F-Super Duty vehicles built prior to 9/22/2004, 2003-2005 Excursion vehicles built prior to 1/10/2005, and 2004-2005 E-Series vehicles built prior to 9/16/2004 and equipped with a 6.0L diesel engine, may exhibit an intermittent I flickering water in fuel (WIF) lamp. The intermittent condition may be more prominent while turning corners, braking, or during uphill/downhill driving.
Some 2003-2007 F-Super Duty and 2003-2005 Excursion vehicles may exhibit a continuous WIF lamp on, even without the presence of water, due to debris in the reservoir or corrosion on the WIF sensor pins located in the manifold.
Some 2003-2007 F-Super Duty and 2003-2005 Excursion vehicles may exhibit both intermittent / flickering and continuous WIF due to corrosion and the lack of new calibration.
ACTION
Use the following Service Procedure based upon the customers symptom.
SERVICE PROCEDURE
1. For intermittent / flickering WIF lamp condition reprogram the powertrain control module (PCM) to the latest calibration using the IDS release B32.11 or higher. Calibration files may also be obtained at the website.
2. If the WIF lamp continuously illuminates without the presence of water, this may be due to corrosion on the sensor pins or sediment build up in the water reservoir.
a. Drain the horizontal fuel conditioning module (HFCM) reservoir and look for significant corrosion debris or sediment in the fluid drained from the reservoir. Remove the WIF sensor and inspect for corrosion on the pins. Remove the WIF Senor by first disconnecting the electrical connector, then using channel locks, rotate the WIF sensor at least 45 degrees counterclockwise. If there is corrosion / sediment on the pins, proceed to Step b. If there is not, refer to PC/ED lead diagnostics and do not proceed with the TSB.
b. If corrosion on the pins is causing the WIF lamp to illuminate, replace the WIF sensor with service kit, following the WIF sensor installation instructions in the kit.
c. If there was significant corrosion debris or sediment drained from the reservoir, clean the housing of the HFCM of any debris following the HFCM cleaning procedure. It is not necessary to replace the Manifold or HFCM assembly.
3. Vehicles with both an intermittent and continuous WIF light due to corrosion are to follow actions 1 and 2 as described above, referring to the vehicle built dates and application.
HFCM Cleaning Procedure
CAUTION Smoking or an open flame of any type is prohibited when working near fuel or fuel vapor.
1. Disconnect both battery ground cables. Refer to Workshop Manual, Section 414-01.
2. Raise and support the vehicle. Refer to Workshop Manual, Section 100-02.
3. Disconnect the fuel pump, heater, water in fuel electrical connectors from HFCM
4. Disconnect HFCM electrical harness from main vehicle harness.
5. Disconnect the fuel hoses from HFCM.
a. Remove the fuel hose retaining clips and discard. Disconnect the fuel hoses closest to the engine
b. Press in the retaining clips and release the fuel hoses closest to the fuel tank
6. Remove the screws and the fuel manifold cover .
7. Clean debris from the HFCM water reservoir housing (max 25 psi air).
8. Install the manifold cover and screws and torque to 441b-in (5 N.m) (
9. Reconnect/reinstall fuel lines.
10. Verify that there are no fuel leaks from the HFCM.
