When I had a 7.3, I never drained the water separator unless the WIF light came on. That thing would eat anything you wanted to feed it. On my 6.0, I drained it often because the injectors wouldn't tolerate low fuel pressure, so its very important to keep the filters clear. On this 6.7, the entire fuel system can be scrapped over water in the fuel, so it makes me feel good to check it from time to time. Plus, there is almost nothing else that needs to be done on this truck and I kind of like to get my hands dirty from time to time. Makes me feel like I did something. Plus I like to use the drained diesel to start up my fire pit.

They do filter it better but emulsified water will still find its way in.

Anyways I will say there is a very fine line when draining where it will leak by oring on valve or will come out of drain.Like 1/8 turn more and it leaks.These 6.7 s are much easier to drain then my 7.3.You had to put a hose on drain tube to get it through the engine to the bottom and sooner or later the valve either broke or leaked by all the time and you had to rebuild it.This is simple on 6.7 to drain.All the room in the world under the truck to move.Get on a creeper,1 min later youre done.

The best method is after you drain say 8/10 o/z is put lid on jar and spin it like it makes a little tornado. Then let sit 2 hours. If you got water its very easy to see.. and for the ones who dont no exactly what it looks like get just drop a few drops of water in your sample jar. You will no what to look for next time.
tries to help then.....

Rex, I'm so so sorry. I was just Private messaged and was told you are actually a guy.
I honestly apologize. I browsed your posts again and now see that.
No more wine while reading on the forum.
again sorry.

I'm laughing my butt off right now. I was like "Rex is a girl? I never picked up on that." Being married for 21 years, I have been conditioned not to question the female intuition on these things. Then I was thinking it would be cool to see a girl driving that beast of a truck down the street.
It has been a crappy night for TV, so it was a welcome laugh when I read how this all played out. Thanks Karen! Who ever said 6.7 was a boring forum?
