Indeed. You will also need the sending unit and the wiring, too.

The voltage stabilizer, whether store bought or home grown, needs a good
ground. Grounding it to the back of the gauge (as is typically done by the
factory) can, in time, lead to the problems you are seeing. Sometimes the bad
ground is within the stabilizer itself. Not so likely in home brew units
with are most likely soldered but the crimp connection on the Lucas units can
corrode and cause problems.
