Dark water in separator

The last two ones that I have checked my water separator the water coming out has been pretty dark. Almost looks like dr pepper or something like that? Up until now the water has always been clear. Has anyone ever seen this and is this something I should even be worried about?

Thanks!

Dr.Pepper! I always get the yellow/green fuel color when I drain, kind of like Mountain Dew

Edit- Do you change your fuel filters? What does the filter look like?

Yes I change the fuel filters every 10000....I have always had small amounts of water when I check my separator, and I check it about once a week at the longest and sometimes more. *When I change my filters they always look what. Would expect to be normal. *A little dirty but actually not much different than a wet new filter. And no, I'm not wetting the new filters before I install them*

I have driven big trucks for years and it is common to find water in diesel. I would be surprised that guys are getting no water whatsoever in their diesel fuel. But hey, if not that's great. I wish I could say the same for any of my diesel trucks.

I took a picture of the water and will post it when I can get it to the right size.

JBB1970 , I'd be willing to bet that you've got crud in your HFCM if your seeing dark fluid. I just serviced mind with 49,000 and it was FULL of crud. I was shocked. Just make sure you get a new gasket ( o-ring ) before you start. I disconnected my front driveshaft for better access. Good Luck...

If you live in a region that regularly has water in the fuel, I would highly recommend an aftermarket water separator and filtration unit. A common rail fuel system won't last long under those conditions

I fill up at half tank when practical. Shell or Chevron when possible, seems to run best on this fuel. Using motorcraft cetane booster as reccomemded by dealer.

As far as having crud in the HFCM I am thinking that is probably the most likely scenario.

I will change the fuel filter and check it out before I hit the road again. I drive about 500-800 miles a week

Thanks for the input guys!
