Fuel Level Sending unit HELP!
I have a few questions regarding it....
1.) Is there an a place one can use to check the wiring on it with out dropping the tank?
2.) where can I find a new one or can I use a universal replacement part?
3.) What are the odds of the low fuel light working while the gauge does not?
The car is an 85 Rx7 GS with a 12 a. I've pulled the gauge cluster, and checked the wires on the back of it (Not sure how it works but I assume its magnetic as there is no motor? The wires all look good however I do not know what plug controls the fuel gauge so I cant check it with the Voltage meter.
Any help would be great! I'm going to hunt down a book for it soon.

Remove the right rear tire. Remove the plastic panel covering the rear of the wheel well. The sending unit can be removed by taking out the small screws around the edge of the circular plate. They are easily stripped. First, test the plug and terminals per the FSM, Chapter 15. A few resistors from Radio Shack can be used to replace the special Mazda tester.

What does the level sending unit usually cost?

I'll look around up here, if not I may just spend the rest of my time with her guessing until I can find a good one on here.
I'm sure someone has Retrofitted something to make it work...

So my best bet is to find the closest Ohm rate I can with a univeral? How deep is the FB tank? The universals are set up for 6"-24" and from what I've seen you adapt them to fit?

In theory any 3 wire universal sending unit should work should it not? Provided of course its the correct length and is the right size? I do believe its a standard 5 bolt set up correct?

Or when the ground contact completely rots off and you connect the ground wire to the ground of the sending unit and it has a mind of its own lol Too much of a pain to mess with the wiring, either I'm going to buy a whole new fuel sending unit with a new connector that connects to the unit or just not know what my gas level is and always fill my tank to the top every day or two.
