Reverse Glow Guage Fix

I just installed the reverse glow guages for my 92 Camry XLE. I adjusted my tachometer, spedometer and the heat so they show the correct showings. My only problem is the gas guage shows I have a full tank of gas when I don't. Does anyone know what to do to fix this?

Just go buy a full tank, drive home and take your console apart and set your fuel gauge needle on a little after F. The fuel low light seems unaffected.
