year? why not replace the original sending unit and be done with it?

any aftermarket gauge can be mounted anyplace you want and the accuaracy will be about the same as original, when full it'll read about full and when empty it'll read about empty, but ..... you're worried about accuracy and want a gauge behind the seat?? grin
