My WIF light keeps combing on no matter how many times I drain it or change the filters. From what I have read from my research so far is that the HFCM on these trucks is ***** and corrodes too bad. If I want to fix this problem and replace the everything that's screwed up, what are the part numbers and parts that I need to be replacing?

Also, my gauge is screwed up from doing my harpoon mod (I think I accidentally over-extended the float rod). I called my local ford stealership to find out what replacement parts would cost, and the guy there said that I would have to replace the whole unit which would be like $550 (if that's the cause, I can just put up with it). Then is started looking on fordonlineparts.com and the most expensive thing they had was like $330. If I can get what I need to fix the problem for under or around $300 then I'll go for it, but if not then I'll just put up with it until my cashflow situation improves. Does anyone know what part numbers and parts I would need to fix this issue also? All help is greatly appreciated. Thanks in advance.

You will get much better prices on Ford parts.

As far as the WIF light, you probably just need the cover to the HFCM (you may just need to take it off and clean it).

 

Not sure this will fix your WIF lite but it did mine.

I removed the drain plug and drilled and tapped it for 1/8th pipe threads. Went to my local hardware store and bought a 1/8th brass 90° M/F nipple, 3 inch piece of 1/8th threaded brass pipe, a 1/8th female union and a 1/8th drain valve. Cost about $10.

I screwed the male part of the 90° nipple into the threaded drain plug then screwed the drain plug back into the HFCM with the female opening pointed down. Then I put the female union on the pipe then screwed the drain valve into the other end of the union. Then I screwed the pipe into the female part of the nipple.

What this did was to get the small amount of water that was in the HFCM to move away from the WIF sensor and go down to the bottom of the 3 inch brass pipe to the drain valve. No more aggravating WIF lite and it reduces the possibility of water corroding the WIF sensor. I normally open the drain about once every 3 months to check for water and normally there is about 1/2 a teaspoon of water that is in the drain. Also, if I were to get some serious water in the HFCM all I have to do is open the drain valve with my hand. No laying on my back and fighting the drain plug.

Also works great when I change that PITA HFCM fuel filter.

Bismic, I tried going to the dicountpartsaty2kford.com link and it doesn't work for some reason, but the other one did. But you wouldn't happend to know any part numbers would you? The only reason I'm kinda sketchy about asking the dealership is I just know how they are about taking the easy way out and just telling you to buy an entire assembly when you only need a small part. But do you know the part number for the stuff I need to fix the float inside the fuel tank? Thanks for the info so far.

DSMMH, do you have any pictuers of what you've done? It sounds like a pretty smart idea, and I know the general idea of what you've done, but I can't get a complete mental picture of what exactly you have done. It sounds like something I could try, but if I do it I want to make sure I use the exact same stuff you did, since I know that way has worked for somebody. Thanks for the good tip. Good engineering

 

Ask them for the HFCM manifold cover, I changed mine 1.5 years ago.

 

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 / 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 Motorcraft.
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.
   1. 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.
   2. 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.
   3. 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

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 (Figure 1).

4. Disconnect HFCM electrical harness from main vehicle harness.
5. Disconnect the fuel hoses from HFCM.
   1. Remove the fuel hose retaining clips and discard. Disconnect the fuel hoses closest to the engine (Figure 2 Number 1).

      Figure 2 - Article 06-22-12
   2. Press in the retaining clips and release the fuel hoses closest to the fuel tank (Figure 3 Number 2).

6. Remove the screws and the fuel manifold cover (Figure 4).
   
   https://www.ford-trucks.com/forums/p...ictureid=23509
   Figure 4 - Article 06-22-12
7. Clean debris from the HFCM water reservoir housing (max 25 psi air).
8. Install the manifold cover and screws and torque to 44lb-in (5 N-m) (Figure 5).

9. Reconnect/reinstall fuel lines.
10. Verify that there are no fuel leaks from the HFCM.

Didn't cheezit just a few days ago state the newer TSB calls for replacing the manifold instead if trying to put a new sensor in because of leakage problems?

 

Sure could be - I just don't recall.

I also do not know the part number for the cover, but call or stop by any dealership for a price quote and they should give you a part number.

 

they did away with that tsb for that very reason. now we just put new manifolds on.

 

The manifold part # is 3C3Z-9B249-AB

 

I would post the pictures but I have not been able to decipher the double speak on how to IMG them into my response. Everything seems to be ON except the "You may not post attachments" thingy. How many gold stars do I have to have before I can post attachments?

That part # is old. The updated part # is 6C3Z9B249A.

 

Thanks Andey

 

Do you have pictures of you're installation and work? I would love to see it!

My WIF light is on constantly, like 5 minutes after i turn on my truck, until i shut it off, have drained it at least 100 times and there isnt any water in it the fuel, but I am not mechanically inclined. How much would the dealership charge me to replace the HFCM or whatever?
