337 Oxygen Leak

If you haven't had your bottles hydrostatic tested you should do so as a lot of FBO's won't service bottles that are out of date.
Your bottles are probably due every 5 years.
The cessna manual says overhaul the regulator at this time along with resealing the filler valve and putting new o-rings in all the plug-in fittings. as for leaks, the guage could have an internal leak or the regulator is not shutting off all the way
Hope this helps
