You probably need a fuel sensor. Usually comes with the fuel filter and are replaced together......hope this helps

It was stored for 11 years. Could it be a rusted or stuck float inside the gas tank?

definately. The fuel sender unit is in the top of the tank and they are prone to sticking. From the back seat of the car you need to remove the storage compartment on the parcel shelf. Once this out of the way you will see a plug in a large bolt looking thing. Using a pair of large sliding grips, undo this and remove the sender unit. Yes, its the long aluminium tube.
