OK now that the legal junk is out of the way. Have a 2008 6.7L with 25,000 miles in my shop right now that is skipping. Pulled the needle connector and it is covered in rust due to water contamination. Had the pleasure of calling the owner and telling him that I could not cover this under warranty. I know it sucks, but I have to return the parts back to Cummins for inspection. If I send the parts back, Cummins will not pay for the warranty repair and will probally void his warranty. The injectors are $1440.00 each and the connector is $108.00. Best case the truck will need 1 injector and needle, 2nd best case is to replace EVERYTHING that fuel touches including all lines, injectors, needles and fuel rail. Worst case is the engine may be toast.
The customer was to say the least, not very happy.
The point of this post is to remind you guys/gals to drain the water from your fuel filter at least once a month.
The camera died after 2 pics, so I could not get a pic of what a new needle looks like, but you can see the rust on the one we pulled out...
