Hello Jack, Notice I didn't say Hijack!! Sounds like your fuel sending unit was original, and if it was, then it could be as simple as the new plug is not making any contact with the old one. Try cleaning it up with "contact" cleaner from Radio Shack or any other electronic parts store source. If nothing is working, then, this is most often the cause. If you want to check both units, all you have to do is connect either one, (outside the tank) and tip them so the float goes to the other end. IE: If it is connected outside the tank and in the upright position, it should read empty. If you tip it over and the float should go to the top, then you should read full on your gauge. Now, I have a question for you. Why did you change out a working sending unit?? Yes, I know an original sending unit is plagued by sloppy readings, but if it worked, (to quote an old military term), why screw with it?? If my suggestions are vague, please contact me off line. I am able to rebuild some of these and might be able to help.
