Fuel Tank Removal

I agree with middle age crisis - some other tips, use a little penetrating oil to help soften the rubber on the grommet. remove the screws behind the filler cap. Take the rubber boot loose (screwed to the floor) from the floor and work it up on the tube, then you can see the O ring gasket on the tank where the tube enters from the inside of the trunk. Spray it down with wd 40 or PB blaster and let it sit a little while - then - twist the tube while pulling it, should come right out. Siphon as much of the old crap as possible and dispose of it - nasty ! I'd also pull the sending unit out as well before dropping the tank, use a brass drift to un lock the ring and yank it out. Its a little easier to do the sending unit with it in the car since the tank wont move around on you as it would with it on the floor etc. You can then have it repaired or buy a new one, about $160 on ebay. Some outfits use a process called gas tank renu which lines the inside and outside with a heavy duty polymer that wont dissolve in gas, they apply it and bake the tank to adhere and cure it. I have a tank done this way and its been perfect for 10+ years.
