Fuel and Temp gauge issues

74 Dart Sport with gas and fuel gauge issues.

Replaced voltage limiter and the fuel gauge came on but it’s off by about 1/2 tank

I replaced sending unit and it reads the same ohms as the old sender at 24ohms while showing 1/4 tank on gauge (went with a 3/8 pick up reason for changing)

Testing at instrument plug shows 24 ohms as well

I have .1 ohm test on printed circuit board.

When testing from prong on board to terminal on gauge I get no continuity?

The temp gauge was showing 56ohms at sender (160 degrees under dash temp gauge)with 56 ohms at plug for dash. (the sender is for aftermarket gauge)

Tested circuit board the the same as above with same results.

Gauge not moving at all

Grounded both gauges and both pegged

At a loss now
