Has anyone tried putting a fuel gage or low level indicator on the older B models? I have a 1979 B7100 I would like to either add a fuel gage or low level light. The tank is so discolored, you can't see the fuel level without lifting the hood and looking in the tank. I have replaced a pricey sender with a marine generic fuel sender on one of my Wheel Horses. It cost less than $20 for the sender, but was fairly easy since the standard VDO flange was already in the top of the tank. So, if I go this direction, I will have to cut a hole in the top of the Kubota tank for the sender flange and mount a compatable gage somewhere on the dash. Does anyone have a better idea?
