Default Nitrous pressure gauge reading zero?

For some odd reason, my pillar mounted nitrous pressure gauge will only read zero. I know I have nitrous and the line is connected. The gauge used to work.

What gives?

Only two things come to mind...Either the line is broken/damaged, or the gauge is faulty...If the valve is open, and you have gas, then most likely its the gauge.

check all connections, maybe you have a bend in the line so it is reading zero. or a fault yguage, but not likely.

If it's an electric gauge the sending unit could have gone bad and you will need to get a new one for the gauge to read properly.

It's a mechanical gauge. I don't know why it would be bad. I have my line ran under the carpet so it's a pain to get to. I'd have to remove the interior and pull the carpet to view the entire feed line. I wanted to rule out everything else before I check that. Nitrous seems to spray fine and it definitely purges.

I also don't hear any leaking sound. I imagine if it was leaking the gauge would still read some pressure?

No ideas before I start ripping the interior out?

Remove gauge. Crack bottle open. If nitrous comes out of the line that was going to the gauge, the gauge is broken. If it doesn't, figure out why (line?).
