Driving home last night... started smelling diesel. Thought it was from my boots, but the smell got stronger and stronger. Pulled in the drive way, opened the hood and bam. 3-4' spray shooting from one of the hard lines on top. Looks like a ferrel nut connection... Towed to shop last night. 1st real problem with the truck since I bought it in 2005. I guess something had to give..

Anybody else had this problem? Probably should just change all the lines, looks like injector lines??

 

If it was the number 4 injector line i have seen threads about a clip thats not tight on it. This gets loose causing the line to vibrate and crack.

 

Ditto on this ^^. Let us know what you find out.
