Water in Fuel!!!! HELP

[stacked73]

My water in fuel light came on yesterday and i have a huge loss of power. So i went to the parts store and got a new fuel filter. My question is should i pull the old filter out, drain the fuel bowl, put the new filter in then crank the truck up or should i fill the bowl back full of fresh diesel before i crank the truck? Or do i even need to drain the bowl at all....can i just pull the old filter out and put the new filter back in screw the top on and crank the truck back up? How long will it take for the water in fuel light to go off after i replace it? I just got the truck not too long ago and its my first diesel so ive never done this before! Any help would be great! thanks guys!

First drain the fuel bowl then install a new filter then simply turn ur truck on the glow plug position and the bowl will fill up on it's own. To be safe cycle the key atleast 2 times and you should be good to go.

If there is water in the bowl, then you have water in you tank. Did you fill up
someplace that doesnt sell much diesel??

Water in diesel can cause bacteria to grow in the fuel and really ruin your
day. It will plug filter after filter.

You might want to consider dropping the tank and cleaning it out.

I filled it up like two weeks ago and this light just came on when the tank go to about a quarter tank. I did replace the filter and the light is still on and still a huge loss of power.....no clue what to do? I guess ill replace the inline filter under the truck next. Didnt see any water when i replaced the one under the hood...all clean diesel.
