Washing out the Wax

[WD40]

Posting this for someone I know. Anyone heard or know about this? In 19000 miles I have gotten the water in fuel light one time.

I am curious if anyone else is having this problem. I have a 6.0 powerstroke, twice in 48,000 miles I could not get the water in fuel light to go off after draining the water from fuel. The first time Ford told me I had to drain the water each month whether the light had come on or not. They replaced one of the switches. The second time it happened I went to Ford in Jacksonville, Fl. and they told me the switch didn't have to be changed but there would be a wax build up in the drain area and they would show me how to clean it. Cleaning involves taking the whole fuel filter system off the frame under the drives door and taking it apart and washing all the wax out of the switch area with spray brake cleaner. I couldn't believe how much wax was in that area, they told me I should figure on doing this about every 15,000 miles if I didn't want to have trouble out on the road. Just wondering if anyone else is having this problem and if there was another solution to repairing without taking the filter off the truck and then taking it all apart.

50k miles and my lights NEVER come on...and i can tell you i didnt
drain the think for almost 10months this last time

'course ive got the heated version too (brown plug).

the dealer in florida might be right about the wax but ask 'em to show
you where it says to do this in the owners or diesel suplement manuals ?

I'd be curious about the fuel you're running... Same place every time?

wd
last summer i had the run in with the wif light
i had to drain quite a bit of fuel from the tank, using the key on. pump run then drain the bowl, it took forever... and i got tons of sand, and some other stuff


the wax washing procedure seems bit strange......, i would take a pipe cleaner and wipe out the fuel bowl real well but never yank teh whole thing off the truck every 15k .....fishy for sure

cant find the picture right now

Mine came on stayed on Only once and Ford changed out the sender on it. I bought the Quick drain Plug that everyone on Here Praises and I have yet to have to Use it. 43,000 on this Truck.

I have found out that there is a TSB for replacing the cover for the fuel water separator housing to fix that problem. So I told him about it and he hasn't gotten back to me yet.
As soon as I know more I will post it here.

I call typical "svc writer" BS on the wax clean out !
another negative for the designer then

I know there certainly was a tsb on the 03's for that - the HFCM - or HFMC or whatever other four letter word we should call the person who designed this !!!!

they replaced the whole unit on my 03 Ex and must have a better design on the 05 cuz I've not drained nor seen a lite in 32K miles...

the replacment units also dont have the heater....(brown plug)

I believe it must be the fuel your getting and its totally BS to have to take it off evry 15k to clean it. I have never had the WIF light come on and just turned 31k miles. I have never drained the HCFM . Then again I run Bio-fuel and believe that makes a differance.
