Hrm. For some strange reason the mod de jeur chose to hack off over half
my reply, so here goes again.

Just out of curiosity, why would you need to replace the gas tank? Does
it have a hole in it or something? To my knowlege theres nothing that
goes wrong with the gas tanks themselves. They're fairly tough plastic(
and fully enclosed by the frame and access panel to boot! So it takes
something major to puncture one.). You also have to remember any stock
the vendors have of theses will be NOS as well.. No one to my knowledge
has ever had a reason to remanufacture these so anything you replaced it
with would be just as old so there's no advantage in doing it if thats
your sole reason. It's just work for no gain. If your doing it because
of debris in the tank, then the pump, pickup and baffle will come out
with the tank in the car.. I think the baffle just requires some bending
to do it, and from there it's just a matter of  getting the last of the
fuel siphoned out and  then cleaning the inside of the tank good.

But to reply to your question.. I seem to recall when I pulled mine  for
the restoration of the car, that for some reason BOTH sides of the foam
was glued, both to the tank and the frame. I ended up having to destroy
most of the foam to get my tank dislodged, and that was even with the
body off where I could access the top.

So my advice to you. If your just wanting to replace the tank because of
age, then your probably best off leaving it alone and in the car. Any of
the tanks you'd get from the vendors would be just as old. If your doing
it for fuel system contamination, then just pull the pump, sender,
baffle, and pickup and clean the tank thoroughly through the access hole.
