Fuel pump locations & spec??? series l

Could some one advise on the fuel pump set up? Do I have a lift(sender unit) and main pump. Can anyone say where I can find the main pump -I can hear a pump running with the ignition on but can't locate it. Can anyone tell me what their impedence is or if there is any spec? Many thanks
