Water In Fuel HFCM Drama - New Manifold Part #?

[drodio]

Hey guys, the WIF light has been on in my 2003 F250 non-stop. I've been going through a list of things to fix it, from least expensive to most expensive.

Now, I need to replace the HFCM manifold. But I'm not sure about the part #, because I see three conflicting numbers. Anyone have an idea which one I need?

Here's an email I just sent to tousleyfordparts.com outlining the issue:

=================

Hello, I need to get a Manifold Service Kit for my 2003 F250.

However, I'm a bit unsure about the part #. I see on your site, you list it as 6C3Z9B249A, but there's also a 6C3Z9B249B and 6C3Z9B249C. Can you please tell me which one I need?

Thanks,

DROdio

Here are the two searches I ran on Ford Parts - Tousley Ford Parts Depot :

well first, im gonna ask is if you have drained the water and or take it apart to make sure the sensor is clean?

It probably was changed because they removed the heater out of them.

Your 03 originally had a new part that included the heater. No longer available.

This changed I think in 05.

The only part# I can find is this: 6C3Z9B249A

Here is an ebay link with a photo.

I'm not suggesting to buy from anyone on ebay.

Tousley would be better.

Yep, about a dozen times. No water. There's actually a TSB out about this issue: https://dl.dropbox.com/u/1096184/tsb06-03-10.pdf

I've also tried (in order of cheapest to most expensive):

1) Replacing fuel filters
2) spraying inside of sensor area w/ carb cleaner
3) replacing just the sensor
4) dropping out the fuel tank to see if it had algae (it didn't -- clean as a whistle)
5) removing the manifold and cleaning it thoroughly w/ carb cleaner
6) and now -- replacing the manifold as per the TSB

But don't know what part # to order between A, B, & C. Even the TSB references two different part #s -- B & C.

@amdriven2liv yeah I saw that one too -- but on the eBay listing it says it's for '05 & up. Mine's an '03. *AND* the TSB says to use B & C, not A for the '03. Hence my confusion.

[amdriven2liv]

They don't make it easy do they.

Thanks for pointing out that for me.

If I remember right B had the fuel heater & connection still in it. C had no heater and used a different pigtail.

[drodio]

@dannyboy950, so the consensus is that I need "C" not "A" or "B"?

Use C ,but order the new plug n play wiring harness with it.

I've found the culprit of the WIF light! It's the Insight CTS monitor I installed.

I've verified with 100% certainty that this is the problem. Whenever it's on and plugged into the OBD connector, the WIF light comes on. Whenever it's not plugged in (or plugged in but in "menu" mode) the WIF light is not on.

I've emailed Insight to see if they have a fix for this.
