Is this hole you are asking about going to be for gauge wires or fuel lines? Your subject implies you want your fuel regulator in the cabin. If you are only concerned with a fuel gauge, Southark hit the nail on the head, but I assume you already know about that grommet considering you're boosted and probably already have wires running through there.
Also.. I know it is probably a sore subject but I encourage you to share the details on your engine failure. It goes a long way to help others not make similar mistakes.
