its a more commin thing then you think my father in law has a shop and thats all he wrks on is cummins and i have replaced more then a few last year

 

I just bought my truck last week and after reading this thread I decided to check the bolts on my truck. Sure enough, #4 was loose. Thanks a bunch for this great tip.

 

Yep! Happened to my dad 3 times and all three times resulted in a piggy-back ride on a tow truck. What is it with the #4 clamp? My #4 clamp has gotten loose twice, but I've never blown a line. Just lucky I guess.

 

We've had 3 of them go at work in the year and a half i've been there.

 

This just happend to my dad a week ago, we replaced the line know truck wont start and the engine light is flashing on and off. pluss a ticking noise is coming from the sylonoid by the air intake.Cant even check the codes with computer just reading "error" Any Ideas?

 

It is my understanding that if your #4 injector line has not broke yet it will. Mine went out on me in Brackettville, Texas 7 hours from home and the closest replacement was in Del Rio 45 minutes away. A local gentleman gave me a ride to Del Rio to pick the last one they had up. As soon as I got home I bought an extra to keep in the truck. I was told that it had something to do with the harmonics and all my clamps were tight.

 

Its enough to **** the Pope off!

 

Had this exact problem the other day! And in the middle of nowhere no doubt!

 

I guess I should just bite the bullet adn get one....soon. Been putting it off.

 

go to cummins eng dlr,get new style clamp which is mounted in a rubber/plastic sleeve, factory rolled clamp 27.00+tx replace old style or keep it in glove box.
