All true, DUB. But, the reality is that the ONLY recourse we have is to bi+ch about the poor quality parts we got and vow to NEVER buy another part from that source. I can accept an occasional miscue...but repeat offenders and stores that just don't care about their customers NEVER see me twice!

Now, before you install that tank, cap two of those fittings with rubber caps and connect the other to a manifold vacuum line. Start the engine and watch the car. Idle rpm is good; more rpm makes LESS vacuum! If it lasts more than 30 seconds, you're good-to-go.

P.S. Tomato cans may not have vacuum applied to them. If not, they don't need a heavy-duty can. Coffee DOES need the heavier can because it is sealed in a vacuum to keep the coffee fresh. Hopefully, your can is strong enough. [Boy, that last sentence didn't sound right, at all....]

I'm really interested to see how this turns out. I like clever solutions to problems, and this is right up there. I hope it holds!

It turned out great. I scuffed the can, etch primed it, and painted it semi gloss black and you can't tell the difference. It's as tight as a bulls *** when vacuum applied. The SEM product is used to hold quarter panels on vans without a problem. The only thing that will separate it is 1100 degrees from a heat gun.

MY ONLY PROBLEM IS I FORGET IF NIPPLES FACE UP OR DOWN WHEN BACK INSTALLED. I wrote in caps hoping someone will answer :-)

It doesn't really matter. If they are turned down, moisture will be able to 'leave' instead of stay in the bottom and cause rusting. But, moisture isn't much of an issue with 'vacuum'.

ALL sealed canned goods are under vacuum be they packed in "tin" cans or glass jars. I'm not sure of how much vacuum but if you've ever opened a Mason jar with your fingernails you know it take quite a bit of force to remove the flat that's just a few square inches. To get the vacuum seal the lid is loosely applied to a container with some intentional "air space" at the top. The can/jar is then heated to above boiling. This forces out the air which is replaced by water vapor (steam). While still steaming hot the seal is secured. The steam in the can/jar condenses back into water as it cools and voila--vacuum.
