I have the factory service manual and looked at what GM wants me to do to be able to replace this fuel tank where some stereo installation idiot (yeah-I wrote that) used a 4 inch screw to hold down the amp behind the passenger seat and screwed it into either the cross-over hose the tank itself.
I am asking if anybody has done this and may have a trick or to or what to really look out for.
From what I can see it seems that the rear drive line needs to be lowered to gain access to the cross-over hose and other hose connections due to they are way up in the...what I call...the ABYSS.

And help would be greatly appreciated.

Dub,
there are many that have dropped the tank without lowering the rear drive, especially for a Manual transmission.
I'm sure they will post to this thread.
There are a few You tube videos showing how to do it.
Don't. have to drop the trans/diff to remove crossover. You do have to drop exhaust. There is a black locking gizmo that can be pried out with a small screwdriver. The white collar rotates clockwise to unlock. The tube is abit stiff.
Now there are tubes inside the crossover tube. Its easy to break the little locking tabs that hold those tubes in place, especially if they haven't been separated in forever. When you pull the crossover tube to remove, you may feel a spongy resistance. That's the small interior tubes not wanting to release from the tubes they are connected to.
This job is much easier if you have an extra elbow or two in your arm. LOL
Good luck.
What confused me what that in the GM service manual it did not state to drop the trans/diff....but when I read the re-install procedure...it DID state to re-install the trans/diff. SO.... it must have been a misprint.

Dub,
You have come through with all our questions about paint/body stuff, so many thanks to you for your expert opinions on that stuff for sure.

Thanks for the kind words. I do what I can.
I will be getting the Corvette in soon to verify that I need to drop the right fuel tank....or if the screw the stereo person installed may have hit the crossover tube.
Either way. I feel this is going to be REALLY FUN! ( and I don't mean in a good way). I feel i am going to be cussing up a storm on this one...I just and a feeling.

Do you have a 2 post lift, or access to a 2 post lift? if so, the job just got a lot easier

Yes..I have a lift. But that means that I have to work standing up. I thought I could just jack it so if I felt like it ...I could take a nap seeing how I would be laying down already
I always remove the rear suspension and diff/trans to access the fuel tanks and crossover, makes it much easier to remove the crossover without any damage, however I do this often where I work and have all the proper equipment. I do not envy anyone who has to do it any other way, Good Luck.

Are you completely removing it or just dropping it down to the point to where the engine does not damage the firewall???

You bring up a good point, I completely remove the rear suspension,(it really is easier than trying to fight the crossover out with everything in the way) but I support the drivetrain with a screw jack and carefully lower the drivetrain once the suspension is out the way.
What cause you to think the installer puncture the tank or the transfer tube what is it doing different sense?
Because when the owner removed the aftermarket amplifier that was mounted behind the passenger seat...one of the screws was 4 INCH sheet rock screw....and when it was taken out.,..the owner intermediately had fuel smells so strong that he can not drive the car without passing out.
SO...it makes complete sense....no fuel smells with the screw installed and sealing up the hole.....and when the screw is out...now he has fuel vapors.
