6.4 fuel water separator

[rum4]

Anyone else have is with that module? Mine has been coming on around every 8 to 20 miles and I have ran 3 tanks thru it and seafoam and it continues to come on. I have drained it each time with little to no water in the fuel I drain. Sometimes it sucks having to pull over where I am to drain that dang thing agian and again...

when was the last time you changed filters?maybe the sensor has went out?

Sounds like the sensor may be bad.

The dealership changed the filters at 10,000 cause it was on but it has not gotten better and I drain it every time it comes on (water/fuel warning) Still the same result. not sure who thought it would be ok for a owner to have to crawl under the truck to drain that PIA....

Ditto on the thought that the sensor is bad......Good luck!!!

well from what i have read on here you dont want to wait til the light comes on....they say by then your injectors are already being eaten by the water and causing break downs.however in your case im leaning more towards a sensor and you should probably try that first

I have heard the same thing from my dealer service writer. If that light EVER comes on, they will deny any claim. Mine is 3 years old and the light has never come on. I was worried before I replaced my fuel filters because nothing would come out of the separator when I opened the valve. When I changed the filters, I found what looked like big clear chunks of salt (I know it wasn't salt, but it looked like clear crystals) inside the separator. I cleaned it out really good, and now it flows freely. I have gone for 6 months at a time between draining that separator, and I have never gotten a light.

I would change the filter myself and get a good look at it to be sure nothing else is in there. I've read here of people not changing the seperator since the light never came on....trust me you don't want the light to ever come on.

Well today they tell me the sensor is bad and they had ordered the part but not all of it so I have to go back in again when they get it all in. They also have to replace the cd player it just quit working...

I have the dealer drain the water separators at every o/f change (5k mi). Not sure that I want to do it myself and risk making a big mess. Fuel filters should be changed every 10k mi for sure.
