My apologies if this question has already been asked, but I did my best to have a look and I couldn't find anything!

I've got a GN Sigma wagon, its on straight gas. Its got an APA industries tank with a 40(empty) to 282 (full) ohm fuel sender thing. It has been retrofitted into the dash gauge, and it never goes past 1/2, and reaches empty when the tank is 1/2 full. I assume this is something to do with the resistance of the dash gauge not matching the one on the tank.
The question is, does anyone know, or know how to measure, the values of resistance that are of the fuel gauge on the cluster? Once I know this, I should be able to either get a new sender, or make a conversion circuit, to make this somewhat more accurate.
Thanks for your help in advance,
Ben.
