    Grounding the sender wire should make the gauge read full.

    I think its the other way around, grounding the sender wire will make it read empty.

    That'll test the guage assuming the wire leading to it is intact. To test the sender you will need a voltmeter of some sort. Either analog or digital. You can set it on its lowest Ohm setting to read continuity. One wire to the sender electrical terminal, and the other to the body of it somewhere such as the top mounting plate. Does not matter which polarity you use. Slowly swing float thru its travel while watching either the needle or the digital readout to see if you find a break in its flow/read out.
