[matty21]

I know this has been discussed before , and for that i apologize , but I can't find the thread again and i lost my manual . Where is it located and how do I do it? My water in fuel light has been on for over a month now , and I want to do it.

Thanks

It is inside the frame rail kind of underneath the drivers door. It has a yellow knob on it.

For how long? Till it stops like the 6.4

I don't think it will stop. Just until the diesel is running clean and there is no water or trash in it.

. If I remember correctly you open the yellow drain knob until the O ring is showing and drain for 25 seconds. I have never seen water in my fuel. I drain into a jar and let it sit overnight.

I think if you open it for a couple of seconds.....it should do it. Looks like the bowl holds 1/2 to 3/4 cups of ljquid. Might also be a good time to change the filter if you haven't done that yet...imho.

thanks guys.
i did it and it drained full flow so i left it about a minute,. it looked clear all along, so i closed it up, then the light came on again after an hour of driving. should i do it again? or is there a reset

also i changed the filter only 2000km ago, so.......?

In my experiences with making bio diesel, it should be pretty easy to see water in the fuel. I like the idea of draining it in a jar, if water is present, you should be able to see it after only a few min if it's not emulsified. If it is emulsified, we would drop some bio on a frying pan(hot plate) and if it popped, it had water(there's a little more to it than that, but its the short version) And, you should only have to drain about a quart or so. You only need to drain out what is in the "cup" if there really is water. The only reason I'm bringing this up is because I've heard this question being asked several times. I hope your water in fuel light is acting up. I walk on the bad side of town at midnight on a saturday night without fear, but water in fuel scares the hell out of me!

All the horror stories I have heard about Ford not warrantying thousands of dollars worth of engine repairs because of poor fuel quality scares the crap out of me too. From what I have heard, as soon as the water in fuel light comes on Ford wants you to kill the truck immediately and have it towed to a dealer.

Not sure how many miles you have on your truck but I do know you have a lot of aftermarket go-fast parts so it may not matter one way or another.

I think you must have gotten a bad tank of fuel. For the light to come on again...I wouldn't want to risk ruining the fuel system...being they seem to be so sensitive to water contamination. To drain the unit for a full minute...must have been a significant amount of fuel you got out.
