Ok, got a 2000 ext. cab LB, with an Auto. mods are Air dog 150, 200 "hp" injectors, stock VP, He had the tubes drilled out to like. .093 I think. not real sure on the size but i Do know that they have been drilled out bigger. has the stock lines. stock charger, and a Built Tranny, and i believe hes got a Torque box OR superchips on it. OK, now the issue. The damn engine keeps blowing injection lines. cracking them in wierd places. ALL the clamps are tight, nothing is rubbing on them, and they haven't been bent or tweeked. About every 12,000 miles it cracks one. im at a loss. Anybody have a clue?. I dont know why he drilled the tubes and not get the bigger lines, its not my truck so i dont have a clue.
Thanks in advance

 

The blue tabs have to be in exactly the right spots or they won't hold with the vibration of the mighty Cummins motors. Need to pull your truck up next to another and compare tabs.

 

never heard of this one .......................hasta be vibrations from lack of or impropper tab placment like our Uncle says

 

I asked him mulitple times if he placed the line holders in the exact spot they came from. He told me he did. ive yet to look for myself. He just moved 30 miles away and i dont see him all the time like i used to. ill let him know to find another 24v and compare the little holders to his and tripple check them. ive ran out of things to tell him. mainly common sence stuff. Everything he told me he looked at would of been the same stuff i would of looked at....wierd
Thnx for the quick response guys

 

He also needs to make sure that the few of them that bolt down to motor mounts are also connected to these mounts. Any deviance from the way they were designed can cause this. Been there fixed that myself.
