You have to drop the fuel tank, which is quite a project, and then 'unscrew' the fuel sender unit. The sender is held in place by a lock-ring that must be gently hammered loose in a counter-clockwise direction. You can then pull the fuel sender unit out of the tank and replace the fuel pump. The difficult part of this whole process is dropping the fuel tank. Search for "drop suburban fuel tank" for instructions on how to do that.
