Here is my fuel level sending unit (1993 RX-7):



Resistance from the armature contact to ground is good (~25-80 ohms through range of motion), but there is no wire attached to the armature.



I can't see a another spot where the other end of the wire is supposed to go from the armature (unless it goes to the bad by the screw...), and I Can't find a pic of someone else's FD FLSU. Please help! I need to put my tank back together!

 

I found the ground path... it goes through a little spring. Nothing is missing from this FLSU. Something else is wrong somewhere outside the tank...

 

My first word of advice would be to NOT have pictures of nice tittay's in the background. It makes everything else out of focus...

 

Oh I just noticed that... what an odd coincidence.

I got it figured out. PO had a walbro installed 90 degrees rotated from the way it should be, and the armature was bent and hitting a baffle in the tank. Rotated the pump so the sock points the right way, bent the armature back to stockish... It works now!
