Range Rover Vogue 03 TD6 Fuel gaur issue

Afternoon this morning it took the in tank main pump out to see if it was causing my fuel issue. On taking out the tanks was 1/4 full now I have put it back turned ignition on and it reads empty and fuel light is on . Any help on how I reset it or calibrate ? TIA

did you remove the battery during all this process?

Hi yeah I did but I’ve sorted it . There was a loose connection inside the tank all fine again Pheeeeew but what a hanging job removing the pump

Hi all . I replaced the inline pump same problem but would t even turn over. I took the pipe that feeds this pump off and when turning on the ignition the diesel was just spraying a little bit. So I purchased an intank Pump only and replaced it myself and now she is working with no issues . Thanks for the help
