Fuel leak causing engine shutdown

[Dernie]

NOTE: complete dealer service with oil change and all fluid levels checked 30 days prior.  2018 duramax with 20k miles. :  
doing a local supermarket run the other day and the limp mode light came on, engine shutdown and pulled off the highway.   Tried to restart ( engine turns over nicely but won’t start).    Got out and found a substantial fuel leak under the passenger side.   Had vehicle towed to local Chevy dealer, awaiting diagnosis.     Any ideas?

Sounds like the DPF fuel injector aka the 9th injector or the line that supplies it with fuel.  That's the only point on the passenger side under the truck for a fuel leak.  The lines and fuel filter are all on the driver's side.
