Title: Gas Gauge Wire
Post by: slammed79 on June 05, 2012, 11:22:38 AM

Is the Gas gauge on a constant hot circuit? I can't figure it out on the diagrams.

Fuel gauge connects to Ignition, Ground and Sender, which is a variable resistance (0 - 93 Ohms; 0=Empty, 93= Full) to ground.

Thanks! I've got a constant hot thats the same gauge and color dangling near my starter. I was hoping that was the fuel wire.
