Cummins Injector Fuel Line Failure

Was travelling with a group friends a couple of weeks ago across Oklahoma (near Muskogee) when his Dodge quit on I-40. Opened the hood and found that the steel fuel line between the fuel rail and injector had cracked and blew fuel all over everthing under his hood.

To make a long story short, it was 6pm on Saturday evening and we were very lucky to get hold of a new fuel line (after a 100 mile drive to Oklahoma City) and get going again. Actually, it was the wrong fuel line but after a couple of hours of roadside redneck engineering in the dark; we made it work. Finally made it to the El Reno KOA at 4am.

Question is: Is that a common failure? The parts man seem to indicate that it was.

  • It's not common, but it happens on occasion. I keep spare parts just for those emergencies and Geno's on speed dial.
  • Look on www.genosgarge.com they sell just the fuel line. Would be smart to have one in a tool box for the effected model years.
  • I wouldn't say common but it does happen on the 5.9. It's always a good idea to check the clamps on the engine every oil change or two.

    I hope you did not bend the line that you made fit too much or your going to have more problems.
  • Was it on a 5.9 Cummins? Then yes. The clamp holding line #4 in place likes to loosen and then rub against the steel line causing a leak.
