Looking for advice on Broken Irrigation System

Looking for advice on Broken Irrigation System

Hopefully this is the right place to ask this. I am trying to fix my sprinkler system. It looks like the three way junction piece cracked and leaked.

Normally I’d be comfortable just patching up the PVC, but not sure what this black tube is and I don’t want to mess it up further. Does anyone know what I’m looking at?
