Welcome to the forum.
Yes, it looks like 1990's was a good decade for gas tanks since no one makes replacements, lol.
I would call a couple of body shops, they may have better resources for finding Ranger gas tanks for a 1996.
Or get your tank repaired or repair it yourself.
Pulling off the bed is only 8 bolts, filler neck and tail light wires.
Or drop the tank from underneath
Once it is out and fuel pump removed flush it out and take it to be repaired or do it yourself.
There is no pressure in a fuel tank except for the weight of the fuel itself, I think regular cab long bed had 20gal tank, so when full, the bottom of the tank would have approx. 160lbs of pressure.
1 pint = 1lb
8 pints in gal
8 x 20gal = 160, slightly less because gasoline doesn't weigh as much as water, 1 pint = 1lb is water weight
