Actually, the first plate encountered under the trunk carpet (right beneath
the ski bag opening if you have one) is held on by three screws.  The
wiring does pass through this plate.  When you lift this plate, it exposes
the top of the fuel tank, where you will encounter the ring that has to be
twisted to release the plate in the top of the tank.  A non-sparking
material should be used to drive the ring off.  But first, you should
detach the high pressure out fuel line (a banjo bolt) and the return and
vent lines (hose clamps) and unplug the wiring connector.

After you twist off the retaining ring, carefully lift the plate it holds
down.  The fuel level float arm is attached and is fairly fragile.  You
also have to disconnect a fuel line and wiring from the bottom of the plate.

The pump on an '87 5ktq is held in the tank by a flexible set of three arms
that slide over hooks on three sides of the pump.  The pump is NOT
connected to the plate at the top of the tank.  It's held near the bottom
of the tank by the rubbery mounting.  It's best to have the tank nearly
empty so you don't have to reach through gas to get to the retaining arm.
