I don't usually post here but this is a dangerous situation. If this really is an injector line, DO NOT DRIVE IT or even start it with a rubber hose patch. That line has thousands of pounds of pressure - depending on the year, 20,000 PSI or more.
Cummins usually has injector lines in stock. You need to replace it properly and torque to spec.
Don't get your skin or face anywhere near that bad line while it's running!
If it's just a rubber hose that has failed, it isn't an injector line. The only rubber lines would be those before the high pressure pump. All the lines between the pump and injectors are metal - no rubber.

If it is rubber then it before the injection pump. Every thing after the injection pump needs to be steel to handle the pressure.
Fuel hose doesn’t usually split, likely chaffed on something and wore a hole in it. If it was cracked, I would get the entire hose replaced.
