If fuel filter is under the car... line next to the filter.
Example: See https://www.fiero.nl/forum/Forum2/HTML/146198.html
return line and EVAP vent are smaller then feed line to engine on many setups.
Can just pull both and return will still have some gas in it. Return line blows bubbles when air is push thru. Many tempted to blow but not good idea. Gas still is poison even w/o lead.

Note that If tank is under ~ ΒΌ don't bother emptying in the car. 2-3 gallon won't spill and isn't very heavy.
If tries to siphon, just pinch/plug the line or tip the tank so gas goes to front.
Put cardboard or scrap carpet on flood so don't scratch off the coating on the tank when using jackstands and/or ramps.[This message has been edited by theogre (edited 07-01-2022).]

The reported capacity of the Fiero fuel pump is 16 gallons per hour. Therefore, it should be possible to empty the tank in about 1/2 hour. A typical car battery has a capacity of 50 amps-hrs. If the fuel pump draws 10 amps for 1/2 hour that is 5 amp-hrs. The battery should have plenty of capacity. If the battery goes flat then it is on the way out and should be replaced. I don't remember exactly how long it took the last time I emptied the tank but it was minutes not hours. It it takes longer than an hour the fuel pump is bad or the screen on the suction of the pump is partially plugged. ------------------

Thanks for the advice ogre. I finally got most of it siphoned out and all the lines are loose, and I'm down to the wiring harness.
I got the plug disconnected and I see it's connected just below the firewall, but can't seem to get it loose from either top or bottom to push it on through. Do I just give it a yank with pliers to pull it out of the loom? Red arrow shows what I'm referring to:

If someone didn't mess w/ it before... Don't think anything beside plug attach to the wires to the tank. But watch out for clip(s) tie-raps or similar between plug and frame hole.
Plug should go thru the hole in frame to drop the tank.
Can be hard to see but frame hole is "oval" shape can snag the plug if turn "wrong."
If has a vent hose etc in the hole, they may need to clear the hole before the plug.
Wires can snag or tangle even w/ over rap that protects them.
