93Ω from the sender is fine.
Spec is "0 - 90Ω" but most read a bit high when full & often the gauge reads a over the full mark too.
But Gauge etc should say Empty a bit sooner Before the F-pump actually sucks air because that can quickly destroy the pump.
Have gauge(s) problems can be a bad gauge but often wiring problem(s) somewhere.
See

maybe
