1987 Ford Ranger

My truck was having issues, it would start up fine then die after a couple minutes. Under the hood I found a cracked piece of hose. It was long enough to cut off the broken part and then reattach. Now my truck seems to be running fine. I attached a couple pictures of the hose, it's the black one. Does anyone know what it is/does?

Thanks
Chelsea

No pics showing up. But if I was to guess I would say it was a vacuum line.
