Gents,
    My cars (Peugeots) have top mounted fuel fuel pick-ups (and gauges 
too for that matter) as illustrated in the link. above both there are 
plastic bungs in the car floor which allow access/ removal/replacement 
of all of these items without disturbing the tank - easy I have replaced 
fuel gauge senders and an in tank pump in 5 minutes (after 350,000km the 
copper segments on the commutator were worn away to the point where only 
the underlying bakelite was visible! ).
    I would have thought that all car manufacturers would have had the 
forethought to put access bungs in the floor ...... if so you should, 
likewise be able to fix the problem properly, and quickly.
