Default dismounting the gas tank

Ok so my fuel pump'* starting to be pretty shot ( I feel like everything'* breaking at the same time, it'* starting to be depressing! ). I tried to dismantle the gas tank and the studs will either don't move or move freely without loosening.

What haven't I understood???

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.

I had my tank out something like 5 times. Friends and I joked that it was held in with velcro. On teh last time.. I think it took 10 minutes to pull it.

Sure looks easy btw you're describing it! Do I have to disconnect to connector that'* passenger side in the trunk or just disconnecting the wires on the side of the tank will be ok?

Side of the tank is all you should need. The wiring in the trunk is likely for your air compressor. If equipped.
