sounds like a bad fuel level sensor, before u go replacing the sensor, make sure all the connections and contacts are good

if it's still under warranty, just bring it in

but yeah, a 463 is the fuel level sensor

You can clean the sensor contacts -

The fuel level sensor is a basically a rheostat on a swing arm, with a float that sits on top of fuel in the tank.

If you pull the fuel pump assembley out (that'll take you 5 minutes), you can use a rubber pencil eraser to clean the contacts of the sensor and likely fix your problems.
