How to replace a fuel pump in subaru legacy turbo?

Under the rear seat, in the middle, there is a trap door. Go through the trap door and just below it is access to the gas tank. Remove the sender unit (removing the fuel lines and electrical connections first) and the fuel pump is atatched to the sending unit inside the tank.
.. note this is for a sedan. In a wagon, go through the carpet in the back. There is an oval cover, remove it, the fuel pump is in there. real easy to remove. Of course unplug the power and fuel lines first.
