This fuel line is attached to the fuel solenoid the old one is a solid steel tube. This is what cummins is replacing it with. Mine cracked on the road and that's how I found out about the new fuel line. You guy's might want to change to the new fuel line if you haven't already.
That's been the replacement line for many years now. Makes it much easier to position and connect to the head feed line block.
I had no idea.... What my repair looked like roadside don't laugh it got me to the parts house. And now..
