Video here, about 4:00min in you get a good look at the 1997 Ranger fuel pump assembly: youtube.com/watch?v=0_9k0wqgmIc
Just a couple of hose clamps, fuel pump is the white cylinder at the bottom
You need to measure current distance from top of assembly to bottom of pump because thats where your pickup tube needs to be, 1/2" from bottom of the tank, with a strainer/sock around it
Strainers/socks seen here:

They need to be large because they WILL get clogged up bit by bit.............and you don't want to have to clean them every year, lol, so the bigger the better
Yes, +1 with RamCharger90 in using the current fuel pump and ditching the mechanical pump
You already have the return line in a 1997
Pressure regulator is not cheap but not too much either
You could just have Key on power to the fuel pump, or use an oil pressure switch with current FP relay
