I just replaced my fuel pump & filter. My gauge reads 1/2 full, but I'm out of gas... how do I reset this?

2003 MERCEDES BENZ C240 STOPPED. COULDN'T GET NO GAS. HAD FULL TANK BUT GAS LIGHT CAME ON. I CHANGED THE FUEL PUMP AND FUEL FILTER STILL DOING THE SAME THING. WHAT ELSE COULD IT BE?
Guess you better re do your fuel pump, the sender is on the fuel pump module. It could be bent or maybe hung on something.
Ok, thank you. I checked the float & it moves freely. But not sure if its hung on anything
