The filler necks are removed by slicing them inside using a hacksaw blade then grabbing with channellocks and twisting/pulling them out.
Clean up the inside bore, making sure the new one fits correctly, then use JB Weld to glue into place.
After that is done, you run a long drill bit in through the expansion hose fitting from the outside to make a hole all the way through. Just be sure to position the filler neck into the tank far enough so that the hole ends up above the inner seat.
