Replace Vacuum Storage Tank
I have a 1969 Corvette with a leaky storage tank that won't hold vacuum and need to replace it. I found an original tank in good condition. Is there and easy way to remove the old tank? Looking at the set up the master cylinder, clutch linkage, etc are in the way. Do I have to remove all this just to replace the tank?
Thanks!

How did you go about checking your present tank? If you tested it in the car [using engine for vacuum source], do you know that the check valve was working properly? It's very common to have a check valve problem. {you may have checked everything properly...just trying to save you money if a smaller item is the real culprit.}
Also, if your tank really has a leak..but no major damage...it's pretty easy to fix once you have it out. Just clean the 'bad' area well and smear some butyl caulk outside of the leak area...remember, it's a vacuum tank...then lay on a thin plastic backing sheet [while caulk is curing] to protect the repaired area. You can re-paint it semi-flat black to pretty it up.

No way could I take the tank out without disconnecting the rod.

I just did this project last week. I had to take out the seat to get out the clutch rod. Then I pulled my tank and refurbished it. It had a crack in it in the backside. I patched it, repainted it and put it back in. My clutch rod was less than great so I ordered a new one of those.

It's a PIA anyway you look at it. Remove steering column. Remove zbar if you have a std. Trans, And you may need to remove the exhaust manifold, or header on the drive side. Like I said it's a PIA.
