FX Impact Leak at angled manometer mounting location

Hi,
I found a tiny leak coming out of the hole where the wrench is inserted. I found the leak out of pure luck. I placed a piece of tape on the vent hole, thinking that it was the source of the leak and found the leak right next to the vent hole. After I degassed the gun, I removed the screw with little resistance. The grub screw threads were clean. No sign of sealant. 🤔
Anyways, is blue loctite recommended or is there anything else better.

Thank you,
Gabe

Utah Air told me to put a small piece of o-ring in the hole before the grub screw.
This sealed it for me .
