Does any one know which wires to hook up to the fuel level sending unit in a fuel cell ? Thanks

 

The wires to it in the tank are purple, I would imagine that they are also purple on the other side of the harness. If yours is acting up, chances are the circuit is fine and the unit itself is crap. I've gone thru 2, they just don't last very long.

 

Thanks, I just got my cell in and cant get the gauge to work. Ill try the purple wire.
