Just pickup up on 08 Lariat crew 4x4. Traded the KR yesterday. On the highway a couple miles and warning buzzer alerting me to drain water separator. I knew where it was on my 95, but not on the 08. Help please, I have to go pick up the new 5'vr tomorrow, and I need to drain it. Oh, this is an AWSOME ride, and the wife agrees. Thanks in advance.

It's right under your driverdoor inside the frame rail. There is a yellow 1/4 turn valve that will drain the water. I suggest a 20oz plastic soda bottle cut in half. That way you can see just how much water was in the fuel and any other debris.
I changed my fuel filter yesterday it had about 145,000 km's on it and , it certenly wasn't clean but no crud on it and to my surprise have never had waster in with my fuel????? Just buy clean fuel.
It's not that simple. Over time, you will accumulate water. You're supposed to check it regularly. I asked three of my friends how to check this when I first bought my truck... all of them drive Powerstrokes... none of them were able to tell me how to check it let alone where the drain valve was. Yes, I looked in the manual, but I still wasn't certain.
You better believe I know how to do it now. And they don't. They're going to get that "water in fuel" message one day and they're not going to know how to drain it.
I had a great saleman.
He crawled under the truck with me and pointed it out, and what to do.
Nice clothes and all under the truck in the gravel parking lot.
I was impressed this once......
He also said dont fool around by keeping driving with that light on.
It could mess up your injectors and they wont be covered under warrenty with water in fuel, no matter if the truck is only a week old.
Also says in the manuel that you shouldnt pull anything till you've got 500-1000 miles on you truck.
