Fuel sender/gauge

[PDH]

No sure if this is the right place for this query. Many apologies if it isn't.

Does anyone know what resistance the fuel sender unit should give?
Mine gives about 30 (full) to 290 (empty) ohms.
Has anyone had reason to check there's, if this sounds right then I was wondering what is wrong with my fuel gauge reading.
It only reads just over a quarter of a tank maximum even though the tank is full.
Could the problem be the voltage regulator?
I take it the idea of the voltage regulator is to supply a constant voltage of 10 volts to the sender via the gauge so that level doesn't fluctuate too much with any voltage fluctuations.

Kindest regards

Have a look at this thread viewtopic.php?f=37&t=22693&p=285991&hilit=fuel+gauge#p285971

Thanks for that.
I have read the thread, my GB wire (wire from the regulator) reads 10.97 volts not 10 as the thread and the manual says.
I note on the elec' schematics that the regulator should be + or - 0.1volt, seems the regulator is u/s.
I assume they are just standard voltage regulators, as long as the pins and physical size are right it should fit OK?

Kindest regards
