The early type of fuel gauge is a "moving iron vane" meter. The later type is fitted with a voltage stabilized heated bimetal type sender and gauge.
The first type was used generally up till the mid-60s in English vehicles.
It is very responsive to fuel movement in the tank.

The later or moving coil system requires a voltage stabiliser (that's the little resistor canister). This type is the bimetallic heated system. Basically this type has a damped gauge and does not have the needle bouncing in the gauge.

They don't mix. You need the correct matching sender, gauge and stabiliser.

For a very good technical explanation of both types look here:
