Default Ohms for fuel level gauge?

Just in case I have to go with a completely different fuel tank. I see on most universal tanks they have a fuel sender. 0 ohms=empty and 90 ohms full. There are others with different ohm readings. Does anyone know the Jaguar ohm readings for the stock fuel gauge? I tried testing my sending unit but its so rusty its not reading anything and I have not started the grueling task of tank removal on the other side

My old faded notes seem to say "20 ohm full, 90 ohm empty".

Hopefully someone will chime in with a concrete answer

Cheers

I don't know if this will help.

I've just bought a new old stock Lucas fuel tank sender for jaguar xj6/12 1976 (hopefully)
Lucas part number smb163??? lucas tbs 5514/022??? Nothing on google

I measured the resistance for you and it varies between 17 to 270 ohms.

The replacement parts seem to be still available. e.g. http://www.jagspares.co.uk/Manners/C...e=10&offset=10
