My Challenger 2021 has developed a very slow leak. I did add one small drop of silicone oil to end of Foster fitting at last fill - still a slow leak. I suspect it may be at pressure gauge as I have tightened it, but it seems like I could keep right on turning it. Do the stems on the pressure gauge bottom out, or are they a pass-through into air cylinder? Any advice on re-doing thread sealant? Thanks for any assistance.

Thanks for reply. No sign of a rubber washer on mine. Of course I can’t find exploded parts diagram for this online. Anybody have one?

The pressure gauge on mine looks like the photograph above. I can't tell whether there's a washer in there or not. Mine doesn't leak, but I did note that the manual advises the owner to tighten that gauge...

I did, just a little, a couple times. Afraid to go anymore. Will look into it further. Thanks.

the ch2021 is a whole different gun and the EVP is only available to service centers like Airgun Revisions.

The reason The number starts with 1764 is because we started this conversion on a standard marauders three years ago.
1764 stands for the model number of the 177 Marauder.
