I'm no real help of the wiring/function of the thing. If I had one out (and a helper) and saw that moving the float didn't move the needle..I'd know ether the unit or it's wires were boogered. I've done that and seen it work. (I mean she said the needle moved correctly).

I read on Autozone where a guy that bought a pump like mine put it in and both the pump and gauge would not work. He pulled it out and reversed the two non ground leads and everything worked ok.
So I made a jumper and swapped the two leads and the gauge went down to empty plus the low fuel light came on but the pump did not work. I took my jumper out and plugged the connectors back in and spliced in a long ground wire that I ran up and connected to the neg battery post and gauge still reads full but of course the pump works.

Yeah, apparently there's no standard when it comes to fuel pumps. When I replaced the one in my YJ, it looked identical to the factory one except the leads were reversed for whatever reason.
