Fuel in exhaust?

[JoJon]

I noticed a little bit of fuel leaking from one of my exhaust joints this weekend, at first I thought it was water, it was fuel. Truck starts and runs fine, plenty of boost, just can't figure it out. I tried doing a search on the subject but no luck, What would cause fuel in the exhaust?

Thanks

Its called slobber.All diesels do it to some extent mainly on startup and colder temps exaggerate the problem.Idling in cold temps also makes it do this.Unless its excessive and you dont have any issues of performance and such I wouldnt worry about it.
