Major leak on a rooftop package unit!!!

Have not seen one this bad in awhile.  Got a call from a fellow in Las Vegas.  He noticed an oiley goo all under his 5 ton package rooftop unit.  He thought it was oil and wanted to know what was going on and the DIY fix he might be able to do .

Maaaaaan, I thought the compressor plug blew out or something big to dump all that oil and gas out at once. I asked him to pull power to the unit and look around at some usual suspects.  He called me back in half an hour with the spot.  It was a pinch off tube that cracked.  Now these come from the factory and once the unit is charged the tube is pinched off and a little silver solder/braze is put in to seal it. 

I walked him through the steps that he would have to go through to get the unit back up and running.

It was a strange one and also on a package unit.  Typically the heavy leakers are the split systems.
