I found the leak it's at the number one fuel line where it is fastened to the injector tube. I'm thinking it could be just the O-ring and I'm wondering if those can be purchased individually or do I have to purchase the whole line.
Expert:  Robert R replied 7 months ago.

The fuel injector lines themselves do NOT have any type of O ring. If you are certain that the line is what is leaking, you will need to replace that #1 injector line.

There is an O ring, but it is at the connector tubes. To check this O ring you must remove the line, and the 24mm injector connector tube hold down nut. Once that is removed you can pull out the injector connector tube. Inspect the o ring and replace if necessary. You should be able to get the connector tube o rings separately directly from cummins. If you go to the dealer they will sell you a complete injector connector tube which includes the o ring...

Keep me posted and let me know if you have any additional questions...

Thank you,
