Morning, So I have a 1999 xc 700 and my wife has a 2001 500 Classic. Hers has the electronic fuel gauge and mine only has the tank cap gauge. I'm looking to put and electronic fuel gauge on my 700. Gauges are readily available on eBay but it seems the sending units are pretty much obsolete. Can't find any on eBay either. Has anyone added a gauge to these sleds and if so what sending unit was used?
