Does anyone know what material the 1/8" meth bung is made of? I want to plug it, I think the bung is also aluminum so I'm going to buy a 1/8" NPT aluminum plug.
What should I seal the plug with? I read not to use pipe tape, I assume I'll need something in there since its under boost.
And on that tip sensor bung.... air flows from the pipe through the screw holes on that bung, is that supposed to do that? Will I have any issues with pressure escaping through there? When I seal everything else and put some air through the pipe I can hear/feel air coming through the screw holes(without screws in there yet).
