The hose in question , air supply for the air compressor , is only subject to boost air pressure from the intake manifold , and if it doesn't have special fittings a universal flex rad hose could be used .
If there are special fitting on the ends then a truck repair shop should be able to fabricate one.

Get your ESN (engine serial number) and go to Register your vehicle. It's a great source for info on replacement parts. You can also call Cummins Customer Service ( 1-800-343-7357 ) and give them your ESN

This will tell you where your ESN is:
