hey guys i'm new to this forum and i am currently trying to hook up the water kit from langdon's onto my offenhauser manifold and today i got it all hooked up but it was leaking out of the manifold, i looked and there apears to be 2 plugs or somthing like that, can't really tell what they are but they are leaking from the bottom of the manifold, anyone know what this is or how to stop it from leaking? thanks
