fuel level sensor on 2000 Pontiac Bonneville

I have a 2000 Bonneville SSEi with the supercharged V6 my fuel gage is not working correctelly. Everything I read about this problem points to the fuel level sensor the question is for the model year 2000 is there a difference between the fuel level sensor for the regular V6 and the supercherged V6 This is something I can replace myself but I need to know if their is a diffrence between the types of sensors. Any help would be great!
