Yup, very common problem on 3rd generation trucks. Anyone owning a Dodge diesel needs their head examined if they don't belong to the Turbo Diesel Register

The magazine is pricless to identify issues like this. Interesting to note that of all the generation trucks, the 3rd generation is easily the most reliable. In every issue of the magazine they list issues with each generation. Most generations have a number of pages of issues. The Gen3 trucks barely fill a page! And I've been a member for years.
This 4th injector hose is the #1 issue with third Gen trucks. Many folks carry a spare just in case.
