Really Stupid Issue

I have a ridiculous issue that I could use some help with.

I kegged a strong BPA that I brewed for a friends party. I am going to bottle the batch using a Blichmann beer gun. Now, I need to switch out the current gas line with a Y adapter so that I can use the beer gun. Here enters my ridiculous issue:

I cannot get my current gas line out of the CO2 regulator. Its screwed in as normal, I haven't removed it since I bought the system 4 or 5 months ago. It just won't budge. Maybe its rusted in the months since it was installed, I don't know. I have tried, with all my might, to unscrew the gas line, but it won't move.

Any ideas?

I dunno....Maybe try putting the beer down and turn the wrench the other way?

Cheers!

You do have the gas turned off right?

Yup!

Gentlemen!
After an epic conflict...
A struggle to remembered for ages...
I have wrestled the gas line valve from the CO2 regulator! It is free! RDWHAanotherHB!
