I keep getting a false water-in-fuel warning. No water comes out when I drain the separator and the light just keeps coming on. Anyone know of a cheap fix??
 
sell the truck. our POS BNSF F450 does it non stop. Makes me want to burn it lmao
 
It's ninja water!! You can't see it !! But it's there.
You'll need to replace the tanks, and all of the lines. If you're lucky, it hasn't started to ninja your nozzles. That sucks.

He speaks the truth.
 
No **** snedge? never followed the fords enough but its always been an issue with our work truck. taken it to ford dealers and all sorts of places and still noone knows!!
 
My '06 Did this constantly for about 4 months.. Took it to Ford and they Replaced the Filter/pump assembly on the frame rail.. solved the problem.. Dads '06 F450 is doing this now also
 
How much did they want to replace the assembly?

Has anyone tried to "douche" the assembly to try to clean it out? (Assuming some deposits are faking the sensor into detecting water.)
 
"Ninja" water, huh?:hehe: :bs:

First time I've run into this.:aiwebs_024: And since I'm a chemical engineer in a refinery, I design the facilites to make diesel.

I need a really good technical explanation for Ninja water. :hehe:
:confused:
How do we remove Ninja water at the refinery?

Ninja water is invisible. The only thing you can do is ask it to leave, and hope the light goes out. :pop: :hehe:

I'm not a Ford guy, I just like to mess with them on the internets a little. :Cheer:

Damn it Snedge!!!! I just choked on my water.:kick::hehe:
 
Or I can try this fix

I did some research. This is what I found. I hope this isn't copywrited! Looks like there is a "douche" procedure...

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.
 
I work at dimension ford and am certified from ford on the powerstrokes, Ive seen a lot of trucks come in with this issue and the main problem I see 99% of the time is corrosion in the wif sensor or just dirt and debris, pull the filter out of the horizontal housing on the frame and pull the water drain plug and spray some brake clean in there the then let it dry up. If that doesnt solve ur problem there is water in fuel housing on the side of the fuel pump/filter housing remove that and then clean it up with brake cleaner. The only problem with pulling that housing is you have to replace it. I has a 1 time use gasket that swells one exposed and wont reseal. On the other hand its a lot cheaper and easier to pull 4 like screws out and spend that little bit of cash then replacing the whole fuel pump/filter housing. Just me 2 cents
