Replacing o-rings on the fuel dampeners behind the fuel assembly .... when they become hard and brittle over time causing fuel leaks with changes in temperature .
I bought aftermarket seals the first time I repaired the leak and about 200 miles latter the seals behind a dampeners ruptured .
The second time I bought OEM Cummins seals .... apparently it's not uncommon to do this job 2 or 3 times according to I have ISX repair groups on Facebook.
