s13 Fuel Level reader questions --- Help

[CalilayneSR20]

Whats up guys.. I have a 91 240sx coupe with a Sr20det swap. I have a kph cluster that everything works but the fuel level .. I traced fuses also even bought a generic fuel gauge and wired her directly to my fuel pump and it doesnt read right. I wired it to my brothers same swap and work s wired his to mine and gives a false read I may think I may have a bad reader on fuel pump. .. have no clue whats going on but any info would help... this thread is open to everyone.
