My fuel gauge indicates empty when fuel,help!

Hows it goin? I was recently driving my range after having fixed the starting issue(blown fuse)  and while driving it slowly jumped from half tank to empty and gave me a fuel gauge fault?however,the tank was half full.I would fill it up half way again and so on untill now,all it reads is empty and the light is always on,what could it be? another fuse?

Fuel level sending unit.  They fail quite frequently on my Blazer .

Could also be a voltage issue..if you're shorting out the ground on the fuel pump...could be an issue.  Not sure if our Ranges have integrated sending units with the fuel pump though..

where would the fuel lever sender be?

Hi well yes they do and they do tend to go out and they are located inside the tanks. What  year of rover?  they can be accessed from the inside of vehicle.   LP's  one sender LM's   two senders
