Re: fuel gauge for bike
When I was younger we had a lawn mower that had a "Cat's Eye" mounted at almost the bottom on the side of the tank. As long as it was amber you had gas. I think it was a hex style made of plastic with a little sight glass built into it. I do remember that it had a round cork gasket for a seal. You just unscrewed it and replaced the gasket. Also that's how you cleaned the tank. Gas will not burn. Fumes will! If I were to drill into a metal tank I would fill it to the top with water and then drill the hole. Any members that do not know what there doing! gas can KILL you. Fumes will turn the tank into a bomb! I think we got the gaskets at Western Auto. It's been years.
