I found the same and did the same as you. But I then ordered Cummins #4 updated fuel line and replaced mine. Convenience/insurance for $40. These lines could break for any number of reasons: metal or insulation inconsistencies, tube design, supplier location....most things have a lifecycle anyway. The lines have tails of fuel at 5-20k+ psi flowing thru them, so that has an effect I think.
