bit of a long shot - golf mk4 fuel sender unit location?

[Twelfty]

basicly the fuel gauge isnt working and i cant find anything as to where the fuel sender unit is located if anyone has a clue i'd really appreciate it as my aunt needs to stop runnign out of fuel asap lol

Its all in one with the pump, lift the passenger rear seat base, there should be an access flap with three screws remove this and the pump/sender unit should be under there..
