Anyone know the thread type of the gas line inlet in the tank ...where the the line goes into the tank? it's either 1/2" National Fine or 1/4" NPT?Can't tell and don't want to cross thread the inlet.

Are you talking about the vent line on top of the tank? Or the outlet fitting in the bottom?

Either way, not NPT threads. The top fitting is a banjo fitting (hence straight threads) and the bottom is a 5/16" reverse compression (also straight threads).

The actual tank inlet is not threaded at all.
