How do you change the fuel line from the gas tank to the fuel filter on a 1997 Saab 900 SE?

you will have to drop the tank. to do so:

unplug the sending unit inside the car (under the rear seat base passenger side under a flap of carpet and a plastic cap there are 2 plugs)

raise and support the rear of the car on jack stands

remove the filler neck bolt under the car

remove the small breather hose clamp and rubber pipe and the large filler clamp and pipe.

remove the purge line will need a special tool or just clip the fitting to get it apart

remove the nut off both gas tank straps

lower the tank (takes a bit of wiggleing)

the line is clipped into the top of the sending unit. press the clip back and wiggle the line till it pulls free.

the process is in reverse to install
