Maximus leak.

[Keyman62421]

Will drop from 2000 to 1000 overnite. Cant seem to locate leak. Gun was not used for several months . Got it out and it was ,low, but i dont remember where it was when i put it up last fall.i thought i would air it up and shoot it . Now it is losing air overnite. I havent had it go dry. Maybe it will. Any experience with similar problem. Ive checked fill and sprayed around . Just dont see the leak.

I'd say there is only 4 places to leak.
1) Fill Nipple
2) Gauge port
3) Valve/Tube seal
4) Valve Poppet.

You've checked the fill probe so that only leaves 3 places. If you soap the gauge and put a balloon on the barrel and neither show leaks then I would say it's the valve/tube o-rings (which is most unlikely). My guess is gauge or valve poppet.
