post picture of the metal cover on the access hole ..
I would do the same procedure 40Gallon tank in a 1990 rust belt vehicle that would be a nasty job doing the tank drop ..

the other reason to do it this way is , in today's world fuel pumps are not reliable poor chineseium ...

I cut the hole at four corners , started by locating center of fuel pump, carefully drill a starter hole for the nibbler.it's a body shop tool. from $25 to $100, but no sparks
My measurements are for 1987 to 1990 forty gallon square bodies.
this fix should work just get the hole correct.
The plate just GE silicone a flat piece of metal larger than the hole you cut
If changing the pump be cautious the lines can be nasty
