MG MG Y Type - fuel gauge doesn t work

try this Franz:

Our gauges are slightly different to that described but the resistances quoted should, I expect, be the same. They are simple units, consisting of little more than a bi-metal strip which bends when heated fed by a variable resistor in the tank.

I just changed my YB to negative earth and it made no difference to the operation of the fuel gauge, only had to swap the wires over on the amp gauge.

Have you checked the float in the tank
It could be full of fuel
