Voltage stabilizer needed for S2 fuel guage?

My friend has a S2 with a twitchy fuel guage. I suggested he wire in a voltage stabiliser to solve the problem. The S2 wiring diagram doesn’t show a stabilizer in the car.
Would the stabilizer cure the needle flutter?
There is some tach bounce as well but he as a MSD ignition box which I suspect is causing the tach bounce.
TIA

My S2’s fuel gauge also jumps around but I dont think it a case of the voltage changing, I think it is a different type of gauge and I dont think they are “damped”
I doubt a stabilizer would cure it, its part of the “charm” of the early cars :laughing:
to see the fuel gauge show “full or empty” when going round a corner …the gauge is just there to tell you if its got fuel in not to tell you how much :laughing: :laughing: :laughing:
Tell your friend to carry a piece of wood dowel to dip the tank…I do :laughing:

I am sure there should be a voltage stabilizer

… Check behind the speedo and tach.

This electromechanical type does go wrong from time to time. Check it is properly earthed. If it is no good replace it with a new one.

You can use better solid state ones - look on ebay.

No Iain, Phil is quite right, there is no stabilizer on the early cars as borne out by the wiring diagram.
