You need the sending unit that matches the body. the 83 tank/sender wasn't fuel injected, the 88 is. The gauge and sender work differently on the newer body.

I looked at the dash diagram for 87-93 Stang - the fuel sender is supposed to be a yellow wire with white stripe that goes to the dash and a black wire from the sending unit that goes to ground. Try the other black wire after checking if they go to ground with an ohmeter.

Did they change the Ohms on the senders/gauges? I notice Autometer said something about early/late Ford on the fuel gauges, or are they talking EARLY Ford?

Just curious....

Yeah the problem there is that you have a Carb'd fuel pump, in an EFI car. Swap the pumps and everything should be golden.

Jester...I have no idea.....Sorry for the lack of help there.
