I've had this Marauder pistol for around 7 years. It started leaking about a year ago. Just ignored it. It would lose most pressure overnight.
Finally diagnosed it with soapy water--leaking from where the pressure gauge screws into the reservoir tube. I have tried 4 ways to seal it--no luck:
-Re-install with yellow gas tape on the gauge threads.
-Re-install with blue loctite on the threads.
-Re-install with both yellow plumbers (gas) tape and blue loctite on the threads.
-Put an o-ring at the base of the pressure gauge.
The leak remains in the same place--right side of the threaded port that the guage screws into, when shouldered and looking down the barrel.
Any suggestions on a way to seal this leak? Should I try a caulk product, or a marine sealant like 5200 or 4000?
