only way to reverse the reading would be to flip your sending unit up side down so that it thinks full is empty, or get an aftermarket 90ohm sending unit and install it in your tank., witch would be easyer. I had this problem when I was restoring my gremlin, AMC used like a 160ohm sending unit that I couldnt find gauges for, so I got a 90ohm univeral sending unit from summit for like $30 I think, may have been less.
