cummins 5.9 fuel line leaks

I worry a lot about a lot of things so I carry spare lines and a 3/4" open end wrench. I wouldn't say the failure is common but it happens enough to be cautious, especially if you go on long trips, etc. You can't just continue running with a cracked line as it is under rail pressure all the time. Rail pressure does go up with more accelerator pedal, from about 5000 psi at idle to a max of about 23,000 psi.
