Fuel Leak '06 DS

I have a 06 Dutch Star with the ISL400 cummins. On a trip to Baton Rouge, La last week the high pressure line from the pump to the injector rail cracked and sprayed diesel at very high pressure all over the interior of the motor compartment and also covered the Jeep that I was towing. We were very lucky that it did not start a fire in the engine compartment, as the fuel was being sprayed in a very fine fog or mist. I was shocked when I looked on the net to find that this is a very common problem on many of the cummins engines and that they actual have a campaign number issued to replace this line with one that has a bracked attached to prevent this. This number is C0805. I don't understand why cummins did not issue a recall but chose to replace these lines as they fail. I guess they have to wait until someone is hurt from a fire or worse is killed! I just want everyone to know that this issue is out there and if you have one of the engines that was produced from 04 or later please check to see if you engine is on the list. I think that we were lucky that we did not have a fire, but were stranded over the memorial day weekend on I49 with an engine that Cummins knew had a high pressure fuel that was going to crack. My engine has less than 12,000 miles on it. Please help get the word out

Hi garyloftin,
This has been known for some time. It was discussed at

This also affects ISC engines. I did receive a campaign notice and had the fix installed.
