Fuel Gauge on Instrument Cluster

Hey guys, hope everyone is doing well. I've noticed in my 2005 Honda CR-V that when I fill up the gas all the way it still shows on my instrument cluster that it's not completely full? Is this is a Fuel Pump Sending Unit issue? Thanks!

Could just be a connection that is not making good contact.(maybe at the connector next to the fuel pump- you could try disconnecting that connector and reconnecting it several times to burnish the contacts).
Sometimes the sending unit on the fuel pump gets coated in fuel additives. Some folks have had luck by adding Chevron Techron Concentrated Plus fuel additive to a couple of tanks of gas. Supposedly a solvent in that helps dissolve that coating.
Could be worth a try esp if you see some Techron on sale.
