Knowing about this for years, reading a few threads, and not wanting to pull a bunch of tanks looking for a good sending unit, (even if I got a good one it is still 20+ years old, so I opted for a new aftermarket one)
I decided to try this method and take a bunch of pics.
the threads I read,//www.fiero.nl/forum/A...130314-2-114616.html//www.fiero.nl/forum/A...090219-2-078597.html
The stock sending unit is dead, it has break in the wire
So I ended up with this one SN38A, I was going after the model shown in one of the thread, I got his one not sure the exact differances.
This is how it came.
A quick test.
Now to take things apart.
The stock arm apart.
Now being the sending unit I got, just bolting up it put the float at the backside of the tank, won't work so I had to flip it around.
So I got the bracket that came with it and bent it up to be able to flip it around, I also bent it so the pivot is at the exact same place as stock.
I decide to use the stock arm, grind it down a bit to fit in the set screw hole, looked good, but with out the extra length to hit the stop, at the top most postion it would off the slide and not read, so I had to bend the new arm to match the stock arm.
The stock arm.
I bent the arm like the stock one.
I did have to cut/solder the sending unit wire to the stock wire, (I replaced all the wires and plugs as they were falling apart.)
Some more pics of it on.
Now it doesn't qiute want to fit in the tank.
But putting the pump in not hooked up and putting the pulsator after I got it to fit in.
You can see here the pulsator is not on yet., this is just to get the pump in, I put the pump in the bracket and the sock on, then lowered the unit into the tank haveing to tip the pump sideways to get it in.
As you can see it does fit, but I had to put on the pulsator after the unit is in, not hard at all, as you can pull most of the unit out up to the sending unit and slip on the pulsator. (or hose if you are going that route)
As always use brass to tap the ring in so no sparks can ever happen.
Now to test with it in.
To test it at the full mark, I just turned the tank upside down.
<---- Don't forget to rate.
Edit to add: This only cost $40
