I had to pull my gas lines out to find a leak.  Funny enough the leak was actually in the connection of one of the factory attached gauges not one of the many added connections.  The gauge must have been bumped or twisted while changing kegs recently since it had not leaked previously.   It was a quick fix and gave me a chance to photograph the whole gas line setup.  See more details on the keezer pages.

Update:

I have switched to a actual beer gas setup. I forgot a few times to set the gas back to low pressure after finishing serving. It would work but user error (me) was the issue.
