Are these sender ohms readings the same for mine

If you know your sender part number or just look up an equivalent one up on the interweb, it usually says the ohm range. That’s how I found mine out.

Should be able to bench test that w a multimeter from full to empty and adjust some bendable tabs if need be to get it within spec.

You can test the gauge w the sender on the bench as well. Yes you will need some kind of 5V source or 12V source into your instrument cluster voltage regulator.
