Default 69 Vacuum Tank Question

My 69 currently has the wrong 3 port vacuum tank. I have the correct 2 port tank but want to powder coat it before I swap them out.

My question is - is there anything inside that I could damage by subjecting it to the 400 degrees necessary to cure the powder?

My assumption is there is nothing inside but better to ask first! I am sure someone has had one of these apart.

Thanks

John

Hi John,
I believe the tank is empty. No valves or anything like that!
Regards,
Alan

As long as the steel of the tank is sound the heat should have no adverse effects.

I would become very familiar with the installation by using the incorrect/old one though.

If the car is not disassembled or if you do not have power brakes, your lucky, but it is still a BEAR of a job to re-install that dude without scaring/scratching it!!

If you do have P-brakes it is even more of a BEAR.

Yeah - has power brakes but I have done this before. And it is a PITA but doable. The OUT & back IN are the issues - the rest isn't bad.

Thanks for the replies. First order of business is to get the 2 port tank powder coated.

One safety thought comes to mind and its way out in left field but I have seen some vac tanks with gasoline in them so be careful of the fumes.

Great point Roger! The tank has been sitting for several years so any gas should have evaporated if there ever was any in there. I will still be very cautious when it goes into the oven.

Gotta love this forum!!!

I am about to pull the vacuum tank on my 70 with power brakes. Is there any way of getting that tank out without removing the power brake booster? My car has A/C, and I looked up under the dash and could barely see three of the nuts, could not see the fourth one. It looks like a nightmare!
