Empty with more than 7 gallons of fuel in the tank usually means you have a shorted sender wire or bad sender.
If you have less than 4-5 gallons in the tank I would not expect the needle to move off empty.

Dead short to ground on the signal wire will drive the needle to E.

90Ω resistance to ground on the sender wire will drive the needle to F.

If you unplug the sender or break the tank ground wire the needle will go to the 3:00 position.
