To pull the fuel tank in your year:
Unhook the hoses to the filler
Disconnect the electrical connector by the back passenger side of the tank
Disconnect the fuel lines by the fllter
Then support the tank with something from underneath like a jack etc.
And it should be, unbolt the two 15mm'* that hold the straps up. The nuts that the bolt is likely rusted into is part of a clip. If the edge of the clip breaks, everything spins and won't come undone.
This is why I automatically pick up a set of straps and some nuts and bolts. Cut the straps to get the fuel tank out of the area. Then w/o the fuel around, you can cut/grind the old bolts out of the way and prepare for new ones.
