I have low voltage to the fuel tank, so the gauge does'nt work. i have traced the blue/yellow wire back as far as i can. where do i look now?


thanks and have a good fathers day

 

My fuel gage dosen't work either. I just figured that the sending unit was busted. It works right when you fill it up all the way and lasts for about 20 miles on the highway and then goes to empty. I have had three different gauges in it and they all do the same thing. Where are you reading that voltage at??

 

I am testing it at the plug that goes into the sending unit on top of the tank, then back from there.
