gauge cluster question

I have a replacement 12 volt fuel gauge for the '51, see pic. should there be some insulation between the center section of the gauge and the housing, or is that to be in contact ?

Re: gauge cluster question

the gauge should be insulated from the dash
use cardboard, plastic, gasket material or any other insulating material
while this is my volt gauge i used gasket material i had on hand for insulation

Re: gauge cluster question

Hi Ogre, I have the insulation on the back of the housing as you have, I would like to be sure of the inside of the casing, is that elongated soldered tin piece to be in contact, making it a ground, or isolated like the back of the cluster ?

Re: gauge cluster question

my bad, i should have googled it before i posted

yes you need to ground that plate
all analog panel gauges work the same; gas, voltage and oil pressure
12v in, ground and variable ground thru the sending unit
