Maybe not....
Although manuals say to drop the tank, on the 1st gens you don't, there is an access panel underneath the back seat that you unbolt and it goes right to the top of the tank above the fuel pump, and you can pull the fuel pump right out that way...
I'm not 100% positive on the 2nd gen's because I haven't pulled that panel yet. But I looked underneath the seat on my 95 and pulled back the material under the seat to look, and theirs a panel that looks like it would be the access to the fuel pump.
It's worth the check, as you can simply flip up the seat and I think their's 3 bolts or so holding in the panel.
On my 85 runner I changed out the pump from under the back seat in about 15 minutes.
