The link doesn't work unless your willing to join and log in.
So what does it look like? It's common for diesel FF's to turn black from the asphaltane (sp?) in the fuel and causes no issues at all but it does make the filter look terrible.

Could rain water be getting in the fuel at the station or bulk plant?

I joined in 2007 and am signed in. I don't know about the rain water. I'm going to change service stations and see. I'm new to diesels and some have said this is normal. Don't know.

Don't know if it's needed or not, but I change fuel filters and oil filters every oil change (about every 5000 plus miles). Might cost a little more, but it only takes once to regret being cheap. I spent a lot (did I say a "lot ... I mean "I spent a LOT of money) when purchasing that truck. I'm not going to take the cheap route now with on-going maintenance!

I was told to change mine every 15,000 miles. Is that a good idea?

I go by the DIC (which does factor in how the truck is being driven) and usually change at about 20% which is usually right around 10K miles. If I'm towing a lot it's closer to 8K or so.

Every 15K is recommended and works fine unless you happen to buy fuel heavily contaminated with water. It is recommended to drain a little fuel from the bottom of your fuel filter once a month. I drain into a clear container so I can see the water, if any is present.

If the filter is coffee black, that's normal. If it has barnacles growing on it, change interval needs to be shortened. I changed mine every 15k on my Cummins Rams.

Well with an 03 Dmax and the known injector problems with the LB7 engine I would rather change the filter every 5000 miles than replace the injectors. Not saying that I won't ever have to, but just want to get as much life out of them as I can.
