The gauges with voltage stabilizers work in a different resistance range. You
would have to change out all of the electrical gauges.
I think the problem with the fuel gauge jumping around may be related to the
condition of the contacts in the fuel sending unit. Maybe try cleaning those up
before trying anything drastic.

Hey Simon,
The Triumph Spitfires and GT6, I believe, had voltage stabilizers for the fuel
gauge. Maybe they could be used in a Healey? I would defer to Michael for an
answer.
Cheers,

Hi Simon, I think that keeping any sort of energy storage device well away
from the fuel gauge circuit is sage advice.
I would suggest that you try this:

Hi,
I?d saved something relating to damping the fluctuations in my fuel gauge. I
don?t recall if it was originally posted here or if I trawled it off the net.
I?d made a few notes and filed it appropriately against some day in the future
when I might get round to actually doing it.
So, my nephew?s fuel gauge bounces around far more than mine and this prompted
me to dig out the article/notes.
First off, I agree that there?s no sense in putting the capacitor anywhere near
the fuel tank.
Having said that, I read the advice that I?d stored so carefully and began to
wonder if I?d understood it correctly.
Is the capacitor really supposed to be wired across the two terminals on the
gauge? Would it have any effect? To put it crudely, but in the language that I
can understand, wouldn?t the fluctuations still come down the Green/Black wire
from the sender unit and hit the gauge?s terminal T? And wouldn?t those
fluctuations still register as such on the gauge, totally unaffected by the
capacitor?
Shouldn?t the capacitor be wired in such a fashion that the fluctuations cannot
bypass it?
Maybe I?m over complicating things and should just try it without understanding
it. Maybe I think too much.
Simon
