My model III project is coming together however I have hit a small roadblock. I had planed on using a standard Kitfox fuel level tube for a gauge which I had purchased ,but when I started to install it I found my fiberglass wing tank has no reinforced points for the threaded fittings to go into just a fuel outlet and a breather outlet. I called Kitfox and they said I must have a really old tank and did not recommend drilling into the thin tank wall and therefore I need some means of getting a fuel gauge that will work ,looking for ideas. Thanks
