Re: Fuel Gauge Help Needed (not typical problem)
From your description, I suspect that the resistor on the back of the dash gauge is bad. I would suggest making sure the fuse is good. Disconnect the brown sending wire at the fuse panel and ground the terminal to a known ground on the truck. If the gauge still goes to full then there is a problem with the gauge, possibly the resistor on the back of the gauge.
