Default steps to replace gas tank in 67'

The last time I drove my car was 1995 and at that time it had been stored for 5 years.
Because of the crap gas available I added a bottle of octane improver .
There was still about 5 gals in the tank in the fall of '95,worst mistake I ever made.
Eventually the "GAS" ate a hole in the tank.

I now have a new tank and am looking for the correct procedure to replace the old one.

Easy one.
Drop the spare tire and bucket.
Undo fuel hose and unplug wiring.
Remove two tank strap bolts.
Drop tank down a bit and prop it up.
From up top, reach through fuel filler hole and remove cap, filler neck rubber and then filler neck.
Rotate top of tank towards front of car and drop it down.
Out in half an hour or less.
Good luck, Greg

If you have undercar exhaust, you will have to drop the mufflers also.

The only issue I had was trying to get the new straps to fit. The old ones were in decent shape, so I cleaned them up and re-used them. I read where others did the same.

The straps are fairly malleable. One of the way to “form” the straps is to rough form the new ones by using the originals as a pattern, get a couple of longer bolts and nuts, install the new tank and straps and use the longer bolts to pull the new straps into position, forming them properly. Then replace the longer bolts with the correct ones.

One other point, if you are replacing the tank with an aftermarket tank with an intank fuel pump it comes with a guard that keeps the right strap from interfering with the plumbing (these tanks pump fuel from the top vs. the gravity bottom feed of the oem tank). This makes forming that strap more difficult and the method above works well. Make sure you use that guard!

Here is a forward thinking thought for you. Assuming you are about to bring the car back to life, what else are you planning on doing? We, the CF have plenty of experience of providing resuscitation of Vettes.

I prefer re using the original straps if they are in good shape, they are already bent properly and make the install go much easier.

Thanks for the input guys.
Bluestripe, I will probably be replacing the brakelines and rebuilding the reservoir.
One concern is the condition of the radiator.

I reused mine. The new straps were not particularly interested in forming to the tank...I'm sure that given enough time (and maybe some heat) they'd have cooperated, but I think they were coming up about 3" short just from me trying to pull them into place. The old straps were in great shape and fit like a glove. Which says something about the quality of the tank, too.
