It sounds like the floats on the fuel sender are stuck or you need to replace the whole fuel sender. It happened to me and i replaced the Fuel sender and fuel pump. Just be careful if you do decide to replace it, the bolts that on sender on the gas tank tend to rust and mine all snapped. Then i had to drop the gas tank... It wasn't fun.. But it definitely sounds like the floats are stuck.

Put in a bottle of Chevron with Techron Fuel Injector Cleaner, GM recommended this for years. The sulfur in the fuel builds up on the contacts and this can happen. Try this first before spending big money on a new sender. This is very common, contrary to popular belief our fuel stinks. Buy Top Tier Fuel if you can. Sunoco, BP, Shell, etc...tend to have better fuel. Top Tier is the way to go, if it is in your area.

What has been said about the fuels of today leaving a layer or film deposit on the sender unit is quite true...also the amount of alcohol in todays fuel allows it to hold more water and that too causes corrosion on the sender assy.
Techron is the usual and most effective "fix" and just a good idea for fuel system maintinence. It won;t do anything to your new BoschIII injectors except keep them clean.

You said it, and it is a pet peeve of mine. DO NOT TOP OFF FUEL TANKS. When the pump shuts off it is full leave it alone. The tank needs expansion room and for the EVAP system to work properly. Rounding to the next whole dollar or what you got in change, if you are paying cash is ok. I have seen people keep topping off the tank to the point the charcoal canister is full of liquid fuel. By this time, it is junk. Then they wonder why they smell gas around their car.
