For some reason, my driver's tire went flat during storage. Well, I've never taken the spare out yet, so in less than 5 minutes, I had my spare out.
Then I got to thinking...
20 minutes later I pulled out the spare tire holder/container. Saw the gas tank and I just had to do it.
I blasted the bolts with some penetrating fluid and let 'em soak overnight. Then my bro and I tore into it the next night. All together, it took only about an hour or so- and I've never done a Corvette either.
To anyone out there thinking about doing this (to check for a buildsheet/tank sticker), it's simple with two people.
Here's all you need to know:
After taking down the spare tire carrier, this is all that's needed:
Drain the fuel tank. I use this line suction tool/hose with a check valve. You just go back and forth till it starts pumping and it'll drain it in no time.
Unhook two wires in the sending unit.
Each side has three bolts ot worry about: 1 bolt for the strap and 2 for the crossmember.
Undo the strap bolts, then push the straps through the rear frame slots.
Ahead, use 9/16 sockets under the frame crossmember, and a small 9/16 socket inside the 'rail. Take out one bolt on each side, but loosen the others to where you can undo them with your fingers, with only a few threads on.
Then, clip your fuel and return lines (both sides)- hey, they're old and you're going to replace the rubber anyways.
Each person uses on forearm on the tank and the other hand unscrews the bolt, dropping the crossmember out of the way.
Only thing that got in the way was my car had a second "vent" line on the driver's side, which had a small bracket and hose.
Swivel the tank forward and drop it down. Then pull it to one side (to gain room for the driver's side) and straight out the back.
My build sheet was toast, with only a few remnants. Oh, well.
