Ok so Iadmit it , i sinned lol. I swapped the interior in my 86gt to all black 87-93 but now im having probs with the fuel gauge reading wrong. I never swapped out to a newer sending unit, and when i put 5 gallons in there itll read 1/8th tank which I know is wrong. the gauge on my old style instrument cluster worked great with the sending unit thats in there right now. Its the sending unit isnt it??

thanks
