The problem is the gauge, not the sender. You can try to calibrate it but I
have never been very successful:

I built one of these but it did not help much:

I suspect the problem is caused because the magnetic coils have gone out of
plumb through the years:

Moving the coils even a tiny bit can cause the gauge to stick on full or
empty. When the nuts are tightened it will also affect the coil alignment.

Subject: [Healeys] BJ-8 fuel sending unit - changed?
All: does anyone know if the fuel tank sending unit for a BJ-8 that is
being sold today has changed from what was original?
After being stranded on the road having run out of gas while the gauge read
? full, I purchased a new unit from Moss Motors. After installing the unit,
it didn?t seem to correspond with what I thought was in the tank. I pumped
the tank out, and it still reads ? full!
Thinking I had maybe installed it in the wrong orientation, I found the
following quote from Rich Chrysler. Being from Rich, I am assuming it is
correct:
The fuel sender is fitted with the screw terminal toward the back of the
car, placing the float forward to the deepest and closest point to the pick
up tube.
Reading the above, it would follow that the sending unit would have the
terminal at one end and the pick-up arm at the other. Problem is, this unit
has them both on the same end. And, yes ? I could just turn it around so
that the float is in the front, but that isn?t solving the problem. It does
read closer to empty, but not completely.
This all raises the question: are these units being made differently now,
or did I get the wrong unit shipped to me? See picture attached for an
example of what I received.
Thanks in advance,
