water in fuel light came on.

[Mike Hickman]

My first diesel truck and got this tonight..
Do I need to disconect the electrical harnesses and battery to drain the water ? ??

[Mike Hickman]

I just took that lil valve looking thing out of the HFCM drained the water/diesel out put it back in we will see what happens ..

Thats all you need to do.

you also need to change your filters

Talked to the server manager at Chaparral Ford And he said if the light comes back on to bring it in under warranty , could be a bad fuel modulator..

Also said just draining the water off should be the only
thing I needed to do ..
Thanks guys for the help..

At mile 300 I got 27 gal of bad fuel, I feel your pain!

Fuel modulator? How about water in fuel sensor. They can become corroded. Deppends on whats really in the fuel and how often it gets drained. Deppending on where you are getting your fuel it may need to be drained more frequently.

The guy called it Fuel modulator, he could have meant fuel sensor but will see Monday it's still under factory warranty ... I have drained it two times this week maybe I'll do it again today .... I have been all over this forum looking at all the TSB of my 06 even have the TSB ready for him Monday ...
But thanks for the info Doug !!!!
