replaced fuel pump - gas reading at 3/4 tank

only problem is i have next to no gas in the tank. what happened? i just removed the gas tank again and removed the pump, messed around with it and reinstalled it but its still reading 3/4 tank. the fuel pump itself works just fine but i wanna know why its reading that and how to fix it. need help quick guys please!

edit:
pic of the new one and stock one side by side.

new one is white. the floater arms are positioned exactly the same...

So just use the gauge backwards. You'll know that a "full tank" on the gauge, means you need gas!

Thats a strange issue you got going on.
