    Hi all, total electrical noob here...

    Fuel gauge is "pegging" all the way to bottom of range, looking for help in learning how I would go about diagnosing whether is actually gauge, sending unit... or perhaps a bad ground?

    Thanks in advance for any insight anyone might share!

    Ideas...

    If it's twin screw, consider swapping gauges, see what works... or not.

    Separate continuity checks on gauge, sender, and wiring might be useful.

    Or that ground thing. Maybe start tracing wiring from one end or the other...
