Elton, Rich Chrysler was the expert in all things Austin-Healey and we miss
him very much, while all I claim to know about is BJ8s, which is what the
original question referred to. As I said, my original sending unit and
another original unit that I have, plus two replacements from Moss Motors
ALL had the terminal and float arm on the same side (toward the front of the
car).
The BJ7/BJ8 Mechanical Service Parts List shows one pictorial of the sending
unit and lets it apply to both BJ7 and BJ8; but the part number listing
shows two different part numbers for the sending unit: 1B2736 for BJ7 and
BHA4435 for BJ8. Detailed differences are shown only by part numbers, which
aren't useful without the drawings that go with them. The pictorial is a
left 3/4 view that has the float arm toward the front of the car in relation
to the fuel tank. No terminal is shown, but that may be because in that
view the terminal is to the rear and behind the body of the unit. I have
an original fuel tank from a BJ7 with the sending unit still installed. It
is in storage and the screws are hard to get at so I can't determine whether
the float is toward the front (as it should be, in the deepest part of the
tank), but the terminal is toward the rear. Perhaps Rich was responding
specifically about the orientation of BJ7 units, but to my knowledge all BJ8
units are supposed to have the float arm and terminal on the same (front)
side. Anyway, it doesn't matter as long as the float goes into the well in
the front of the tank.

My BJ7 fuel sender, which is the original, has the screw terminal to the
back of the car and the float towards the front, which is exactly the way
that Rich Chrysler said.

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,
