Benjamin I degassed my Benjamin Marauder and now it leaks.

There is a weeper hole on the back of the gauge.
It is there to allow air to escape when the gauge is bad.
Buy a new one.
In fact buy two and the problem will never happen again.
Hint: Make sure there is NO..NO air in the gun before yo remove the gauge.
Thanks Frank. Is there a weeper hole in all gauges or just the ones that go in the Marauder?

pretty much so,
here's the gauge you need and the O-ring should be a #6 buna nitril,
  • 7/16 in. O.D. x 5/16 in. I.D. x 1/16 in. wall thickness, Ace hardware or home depot should have them
