Get under the car and unhook the hoses, use two wrenches so you don't twist
the rigid pipes, then put a jack under it and remove the 4 bolts that hold
it then lower the tank down, took about a half hour to get it out the first
time I did it.
 
Thanks for the response. Seems straighforward. however, I am stuck
on how to disengage the wire and fuel line cluster accessible through
the trunk. one wire is clipped and removes easily. the others seem
to be hardwired. there is a ring clamp on one fuel line, but another
seems to be pressed in. Then there is the odd lid/receptical
contraption that covers the fuel gauge sending unit, etc. Can't seem
to unscrew it. Does it take a special tool?

Thanks for any advice.
 
That's why I said jack up the car and get under it, the coupling is under
the car near the tank, the hose is hard sealed to the tank sender/pipe unit.
There is a special tool the remove the bung nut but you don't have to remove
it to drop the tank, I didn't have that tool on my dad's car which is why I
dropped the tank in the first place since I couldn't get a good angle on it
with a screwdriver and hammer. I'm about to go try the same thing on my 242
tomorrow as the in-tank pump failed.
 
Tank's out, being vatted.

sending unit dangling, needs replacing.

There are two fuel lines. One has a ring clamp and can be removed
from the sending unit. The other seems to be a rubber coated metal
tube. Does it disconnect somewhere before the external fuel pump?

Then there are the electrical wires leading to the sending unit top.
They appear hard soldered. So to replace are we talking cutting, then
splicing back for the new unit? weird.

Thanks for any experienced advice you have.

The sender's wires and the second hose are connected about a foot away
from the sender, look for the connections there. You may have problems
with the hose connection due to rust, make sure there's no fuel leak on
reassembly.
