New TQ spec on the tubes is 41 ft lbs.

 

Here's the latest- I have replaced lines 1,3,4&5- I'm still leaking from what looks like cylinder 3 where line goes into injector- if the cross flow valve turned would this cause a small leak? I am not leaking as much diesel as before but on top of the motor under the high pressure lines is still getting wet - frustrating!

 

Did you put some light oil on the cross over tube threads and rail threads and tighten the flares before the hold down?

 

I used a back up wrench for removal and install and torqued to specs. I didn't use oil on everything but kept it as clean as possible
