If anyone is about to replace their fuel sending unit or fuel pump and has it removed from your 2003 GT Mustang gas tank, can you please take your sender's empty and full ohms value readings before you reinstall it, and share those readings with the rest of us. These ohms readings will play an important part of troubleshooting your fuel system if you continue to have incorrect fuel level gauge readings after you replace your fuel sending unit. I forgot to take the readings when I replaced my fuel pump module assembly. Thank you for your support, Tommy.
