Yeh, the fuel gauge should be sorted. Just have to get a couple of bits.
What I am currently attempting to do is use the existing temp gauge as a battery amp meter.
I just did a couple of careful measurements with the scope & the dmm.
Minimum gauge gives 556 ohms across the variable resistor. The scope showed the pulse amplitude of 2.54V.
Max gauge gives 33.5 ohms across the var resistor & an amplitude of 0.54V
