Fuel Gauge

[Lextreme]

I added a secondary from one of the Deuces. I would like to hook up a second fuel gauge. Looks like there only ONE wire going from the fuel level sensor to the gauge. I tried either inlet from the gauge but no signal. Any idea? I even ground the fuel gauge. Is it possible the fuel level sensor is bad?

Never trust the fuel gauge on a MV. There are two wires going to the fuel gauge, 1 has 24 volts, one grounds to the sending unit. It varies it's resistance based on the amount of fuel present and what the float level is at. Back to my first sentence, If you believe a fuel gauge in you're Deuce or any other MV, get a good pair of walking shoes because you'll need them. I don't take my truck out of the yard unless I can see fuel in the strainer. In my Deuces case, that should mean I have at least 20 or 30 gallons of Go Go juice but the gauge will only read about 1/2 a tank. It also ran out of fuel at 1/4 tank one time. I use the "visual" check from now on and my gauge thinks it's "working". I just don't trust it too much.

For some reasons, my fuel level sensor only has ONE wire... Perhaps the ground is the truck body already...

YES ONE wire, it goes to the sender, the sender is grounded to the tank, A lot of people will ADD a ground FROM the TANK to the FRAME.

Maybe run a switch that both go to one gauge the xm818 I have has it that way and you just go back and forth

The Fuel Gauge on a Deuce is strictly a serving suggestion.
What are you doing with the fuel return ?
Nice truck in your avatar BTW
