Me and my buddy changed his fuel pump on his S-10. It's not really that bad to drop the fuel tank, just make sure you have as little gas in it as possible. Be sure to use a brass mallet to knock the ring loose around the fuel pump, don't want to be creating any sparks around the fuel. Once you get the ring unscrewed the pump will come right out.
