fuel gauge no longer works after pump install

i installed a walbro pump and now my fuel gauge is dead. its not reading zero, the needle is hanging all the way down. i was very careful during the install not to bend the floater or anything. i wired the pump correctly and put everything back the way it was. anyone know whats up?

Take the pump out. Turn ignition to ON position. Move the floater.

Look for any wires messed up along the harnesss/connectors.

I can’t think of anything else that woudl cause it to malfunction.
