the gauge is original so i assume.. 30? and the sending unit is a 30-90 unit. the thingamajig is an electronic voltage reducer which was suggested to use (purchased from lmc). however, all of the gauges are original which i would think they would all need a reducer, yet they all work aside from the fuel... Suppose first things first is try to run a direct ground line to see if i get anything and then go from there. Appreciate the direction!
