I have an older Shun Sung Career 707 II that has a slow airleak even after I replaced all of the anterior chamber seals. The leak seems to be coming from the gauge section. Any ideas of where my problem is coming from?

Hello Try contacting Will at Saddle Mountain Gunsmith he does a lot of tuning on those guns, he probably has a seal kit and can put you in the right direction of the problem. Hope this helps Eric

Its likely leaking at your check valve where you stick the probe in to fill try soapy water see if it bubbles there.
If so then degass the gun use a c type spanner wrench to unscrew the upper tube retaining trim collar then flip that seal likely a red or pink disc.
If it's leaking soapy water test on lower cylinder you need to remove both retaining collars after degass then slide the entire trim housing around the barrel and both airtubes it's one piece should just slide off unscrew the threaded barrel protector first replace the o-rings you see after sliding it off.
