PMI nitrogen tank

[Mallagant]

I have a PMI 68/3000 nitrogen tank that will not hold air, i believe that its leaking out of the gauge on the screw in portion of the bottle, any ideas about how to fix this?

You can find exactly the leak by using soapy water. You will see bubbles there.
To fix the leaking EMPTY the bottle from air ( be sure twice that is empty ) unscrew the gauge, put teflon or Loctite 542 and put it again in place. With Teflon you can put air immediatily, with Loctite you have to wait to put air.
Hope it help's
