I would like any info on a fuel gauge either with sending unit or even if there was one that mounted at tank.even though you would have to look at thru fuel door.looking for ideas and part # for my 4106 thanks

My 4106 has a momentary switch and a fuel gauge in the fuel door opening.  It doesn't work, but I thought the idea of putting it just above the tank was neat.
