I purchased a spare line from my local cummins shop for $24 a couple years ago. I still need to purchase the 19mm flare nut wrench instead of just the open end for the install.

Same here^^^^
I need to do the same in order to use my torque wrench. Again, anyone clear on what the preferred torque is on these injector lines? Just curious for future needs...

Update: After all this time I finally got the new #4 line... Installed it and fired the truck up... No leak while idling

I got her on the road at night and all of a sudden she sprung another really bad leak. I cant do anything about it tonight... but the mess she made is 10x worse than it was before.. Maybe I didnt torque the sucker down tight enough. Can you even get it tight enough to the cylinder head with an open ended wrench? Or maybe that wasnt the problem at all.. literally when i parked the truck it looks like a swimming pool of diesel underneath..

Any thoughts guys? Busted fuel hoses? Injector pump? Ideas?
