03 Sentra trouble code

hi people..wonder if anyone can shed some light.. my daughter's 03 sentra is showing a trouble code "p0462" which is a fuel level sensor A circuit low input...Can anyone tell an old school guy what this means in English, and how to rectify it..??Thanks in advance,,,

Could be fuel sending unit going bad. It is located in that gas tank. you have to take the tank out to get to it. If you are lucky you can get to it through the trunk.

nah, you can get to it through the back seat, there are details on how to remove it on nissans website under tech, or you could visit powertechimports.com and look under turbo install, they tell you how to remove the fuel pump assembly, i believe there is an active recall on 03's for fuel pump issues
